If your pain feels burning, shooting or electric, or comes with tingling or numbness, a nerve is more likely involved. If it feels dull, achy or sore, stays in one spot and eases with rest, a muscle strain is more likely. Many back, neck and leg pains show a mix of signals, so the pattern matters more than any single word. Write down where the pain is, where it travels and what makes it worse. Those notes help you spot the warning signs that need fast care, and they are what a clinician will ask about first.
Nerve pain vs muscle pain at a glance (as of 2026-11-11)
The table below gathers what each named source says. Each row cites its source in the cell.
| Feature | Nerve pain | Muscle pain |
|---|---|---|
| How people describe it | Burning, stabbing or electric shock-like, plus tingling, numbness or “pins and needles” (Cleveland Clinic) | Dull, achy, sharp, throbbing or cramping (WebMD) |
| Tingling or numbness | Listed as symptoms (Cleveland Clinic) | Uncommon with a muscle strain (Pain Management Specialists) |
| Where it goes | Can radiate along the nerve’s path, such as from the lower back down the leg (Pain Management Specialists) | Usually stays localized to the muscle itself (Pain Management Specialists) |
| What makes it worse | Movement, sneezing or coughing, in sciatica (NHS) | Movements such as coughing or laughing (WebMD) |
| Weakness | Can lead to related muscle weakness (Pain Management Specialists) | Typically does not cause weakness (Pain Management Specialists) |
| Common causes | Diabetes, shingles, chemotherapy, spinal nerve compression or inflammation, among others (Cleveland Clinic) | Overuse, overstretching or lifting something too heavy (Pain Management Specialists); a common cause of back pain is a strain (NHS) |
| Response to rest | May not improve as quickly (Pain Management Specialists) | Often improves with rest, ice and over-the-counter pain medications (Pain Management Specialists) |
How does nerve pain differ from other pain?
The Cleveland Clinic neuropathic pain page says nerve pain arises when the nervous system malfunctions or is damaged, so damaged nerve fibers send incorrect signals to pain centers. Nerve pain can also show up as allodynia, which is pain from normally painless touch, and dysesthesia, which is an unpleasant or strange sensation.
Other pain works differently. WebMD’s nociceptive pain article defines it as “the discomfort you feel in response to damage to your tissues.” That kind most often comes from injury and commonly affects muscles, joints and bones.
How do I know if side pain is muscular?
Pain Management Specialists, a pain practice in Rockville and Frederick, Maryland, describes a strained muscle as an injury to the muscle fibers. The pain usually feels like soreness or a dull ache, with stiffness or tenderness in the area. Use these questions to check your side pain:
- Is it tender in one spot and stiff when you move?
- Does it stay in the muscle rather than travel?
- Does it ease with rest?
- Is there tingling, numbness or weakness? If so, a nerve may be involved, according to the same clinic.
Pinched nerve or pulled muscle: where you feel it
A pinched nerve happens when surrounding tissues put pressure on or irritate a nerve. A bulging spinal disc, called a herniated disc, is one example, according to Pain Management Specialists’ strained muscle guide. The location changes the pattern.
Neck and shoulder
A pinched nerve in the neck may radiate pain to the shoulders or arms. A muscle strain stays local. Muscle strains are most common in the lower back, neck, shoulders and legs. Cleveland Clinic lists frequently dropping held objects among the reasons to call a provider.
Mid back and shoulder blade
The NHS back pain page lists pain between the shoulders rather than the lower back as a reason to see a GP. A common cause of back pain is a strain, which is a pulled muscle.
Lower back
A strain is a common cause of back pain. A pinched nerve in the lower back may cause shooting pain down the leg, which is sciatica, and may weaken leg muscles (Pain Management Specialists). The NHS says back pain may occur with sciatica but is usually less severe than the leg pain. It also says you probably do not have sciatica if you only have back pain.
Leg
The NHS sciatica page says sciatica usually affects the bottom and back of one leg, often the foot and toes. It describes “a sharp, burning pain down the back of the leg,” plus tingling like pins and needles, numbness or weakness. Pain may get worse with movement, sneezing or coughing.
Can nerve pain feel like muscle pain?
It can be hard to tell from words alone. WebMD says nerve pain is more often described as burning, shooting, numbness, tingling or electric shock. Muscle and tissue pain is more often dull, achy or cramping. Sharp appears on the muscle list too, so pair it with where the pain goes and whether numbness comes with it.
Can a muscle strain cause nerve pain?
Pain Management Specialists says a strained muscle generally won’t cause tingling or numbness. Cleveland Clinic’s causes of nerve pain include nerve damage from trauma or surgery and spinal nerve compression or inflammation. A muscle strain is not on that list. The NHS back pain page does list a strain, a slipped disc and sciatica as separate causes of back pain.
What causes nerve tension in the neck?
The usual explanation is pressure. Pain Management Specialists says a pinched nerve happens when surrounding tissues press on or irritate nerves, and a bulging disc is one example. Cleveland Clinic lists spinal nerve compression or inflammation among the causes of nerve pain.
What does neuropathy feel like, and can it cause muscle pain?
The NHS peripheral neuropathy symptoms page groups the symptoms into three types. Muscle cramps and weakness appear in the motor type, so yes, muscle-like symptoms can be part of neuropathy.
| Symptom type | Symptoms the NHS lists |
|---|---|
| Sensory | Pins and needles, numbness, reduced sense of pain or temperature (often in the feet), burning or sharp pain, pain from light touch, poor balance or coordination |
| Motor | Twitching, cramps, muscle weakness or paralysis, muscle wasting, foot drop |
| Autonomic | Dizziness on standing, rapid heartbeat, abnormal sweating, bladder and bowel changes, among others |
Can nerve and muscle pain happen together?
Yes, and sciatica is the common example. Back pain may come with sciatica, but the leg pain is usually the stronger signal, according to the NHS. The NHS back pain page also lists many possible causes of back pain, and a strain is one of them. Cramps and weakness can appear alongside nerve symptoms, as the neuropathy table above shows.
Common mix-ups
- Sharp is on the muscle list too. WebMD includes sharp in its description of muscle and tissue pain.
- Coughing and sneezing show up on both lists. Muscle pain can worsen with coughing or laughing (WebMD), and sciatica can worsen with sneezing or coughing (NHS).
- Back pain alone points away from sciatica. The NHS says you probably do not have sciatica if you only have back pain.
- Numbness in the feet is on the neuropathy list. The NHS lists numbness, pins and needles and burning in the feet among neuropathy symptoms, so a pinched nerve is not the only possibility.
Warning signs that need prompt care
Go to A&E or call 999 now
The NHS sciatica page lists these. Do not drive yourself.
- Sciatica on both sides
- Severe weakness or numbness in both legs, or getting worse
- Numbness around or under the genitals or around the anus
- Difficulty starting to pee, being unable to pee, or losing bladder control
- Not noticing when you need to poo, or losing bowel control
The NHS back pain page adds chest pain, pain after a serious accident, and changes in genital sensation or sexual function. Cleveland Clinic lists severe pain, numbness or weakness that is “quickly getting worse,” a fast or irregular heartbeat, trouble urinating, and dizziness or fainting.
See a GP
- Pain that has not improved after a few weeks of home treatment, is getting worse, or stops you doing normal activities (NHS sciatica page)
- No improvement after a few weeks, stopping daily activities, unexplained weight loss, a lump, swelling or change in the shape of your back, no improvement with rest or worse at night, pain that is worse with sneezing or coughing, or pain between the shoulders rather than the lower back (NHS back pain page)
The NHS back pain page says to contact a GP or 111 urgently if you feel hot, cold, shivery or unwell, or have sudden severe or rapidly worsening pain.
Call a provider
Cleveland Clinic says to call a provider for numbness, tingling, muscle weakness, uncontrolled twitching, or frequently dropping held objects. For more on timing, see when to see a doctor for back pain.
Who examines nerve pain and muscle pain?
Start with a GP or primary care clinician. They examine the symptoms you describe and decide whether a nerve needs checking. If nerve symptoms persist, a neurologist is the specialist who examines them. A physical therapist works on movement and muscle problems. The NHS sciatica page says to see a GP if pain does not improve after a few weeks of home treatment.
To confirm whether a nerve is involved, a clinician examines the symptoms and reviews your history. Bring your notes to that visit.
How is TENS different from vagus stimulation?
The NHS TENS page describes a small portable machine that sends a weak electrical current through sticky pads on the skin for temporary pain relief. It says “TENS does not work for everyone.” Cleveland Clinic’s TENS page says “TENS therapy works well for a lot of people,” and that it “tends to work better for some than others.” The U.S. rule for TENS for pain relief identifies it as Class II, a device “used to apply an electrical current to electrodes on a patient’s skin to treat pain.”
A 2018 Cochrane TENS fibromyalgia review by Johnson and colleagues concluded there “was insufficient high-quality evidence to support or refute the use of TENS for fibromyalgia.”
Where does the vagus nerve fit into nerve and muscle pain?
The vagus nerve runs through the neck, and Cleveland Clinic’s vagus nerve stimulation page describes it that way. Researchers link it to the autonomic nervous system and often measure it indirectly through heart rate variability. Researchers have tested vagus stimulation for several pain conditions. Here is what each study reports, with its people, comparison and length.
What the pain studies report
| Study | Who was in it | Design, comparison and length | What it reported |
|---|---|---|---|
| Eid et al., 2024 review (BMC Musculoskeletal Disorders) | 6 randomized trials in adults with low back pain | Systematic review of those trials | Concluded: “There is still no evidence to support the use of transcutaneous vagus nerve stimulation as a viable therapeutic rehabilitation strategy.” |
| Tavares-Figueiredo et al., 2024 study (Journal of Clinical Medicine) | 30 adults with chronic low back pain, with a pain score of 40 or more out of 100 | Open-label single-arm pilot with no control group; device used 30 minutes daily for 3 months | At 3 months (24 analysed), pain fell 22.5 mm on a 100 mm scale (p < 0.001); 51.9% reached a reduction of 20 mm or more; Oswestry Disability Index fell 11.9 points; no serious adverse events |
| Demircioglu et al., 2024 study (Complementary Therapies in Clinical Practice) | 60 patients with chronic low back pain | Auricular vagus stimulation plus home exercise vs conventional rehabilitation plus home exercise; 5 days a week for 3 weeks | Both groups improved on mobility, function, depression and sleep; pain level, endurance time and trunk flexion strength improved more in the stimulation group (p < 0.05) |
| Likar et al., 2023 review (Schmerz) | 1105 patients treated with auricular vagus nerve stimulation across the included studies | Systematic review: 20 chronic pain studies, 10 acute postoperative pain studies, 7 experimental acute pain studies | Three randomized trials in chronic pain showed pain reduction for up to 12 months; “Overall, aVNS was very well tolerated.” |
| Pellow et al., 2025 review (Scandinavian Journal of Pain) | 813 people across 10 articles (763 given nVNS); nVNS studies included 603 people with headache or migraine, 138 with fibromyalgia symptoms and 22 with chronic low back pain | Systematic review of randomized trials, 2010 to 2023 | Moderate to high quality evidence that nVNS reduces headache frequency and is well tolerated; “insufficient literature exists to support either approach” for chronic pain conditions |
| Lange et al., 2011 (implanted vagus stimulator, fibromyalgia) | 14 people with treatment-resistant fibromyalgia | Open-label phase I/II trial with no control group; 3 months, with follow-up to 11 months | 5 patients met composite efficacy criteria at 3 months; 2 did not tolerate stimulation; the authors wrote that “further research is required” |
| Dolcini et al., 2025 pilot (Clinical and Experimental Rheumatology) | 18 patients with fibromyalgia | Single-group pilot; 30 minutes, 5 times a week, for 4 weeks | Widespread pain index fell at week 2 (p = 0.03) and week 4 (p = 0.004); sleep (PSQI) improved at week 4 (p = 0.02) |
Most of these studies are small, and their authors ask for larger, longer trials. Each result belongs only to the device and people in its row.
FDA status of vagus devices
FDA decisions cover specific devices for specific uses. The table lists what each record covers.
| Device | What the FDA record covers | FDA status |
|---|---|---|
| gammaCore, applied to the side of the neck | Migraine, cluster headache, hemicrania continua and paroxysmal hemicrania, including preventive and acute pain uses | FDA cleared, 510(k) K211856, decision date 2021-09-10 (Substantially Equivalent) |
| Vivistim System (implanted) | Vagus stimulation during rehabilitation therapy to reduce arm motor deficits in chronic ischemic stroke patients with moderate to severe arm impairment | FDA approved, PMA P210007, decision date 08/27/2021 |
| VNS Therapy (implanted) | Partial-onset seizures, approved July 16, 1997; depression, added June 2005 according to the FDA summary | FDA approved, PMA P970003 |
| Consumer vagus devices (neck or ear wearables) | Stress and sleep, described by makers as general wellness uses | General wellness, per the maker’s description |
Cleveland Clinic’s VNS page says external devices exist, and that “The long-term side effects of commercial VNS devices are yet to be fully known.” The implanted Vivistim and VNS Therapy systems are surgical devices, not the consumer neck or ear wearables.
What the words on vagus devices mean
| Term | What it means, per the source | Source |
|---|---|---|
| FDA approved | Highest-risk devices “generally require FDA approval of a premarket approval application” | FDA’s “Is It Really ‘FDA Approved’?” update |
| FDA cleared | Moderate-risk devices may be marketed through “510(k) clearance” after showing they are substantially equivalent to a legally marketed device | FDA’s “Is It Really ‘FDA Approved’?” update |
| Registered | “Mere registration of an establishment or listing of a drug or device does not denote approval” | FDA’s “Is It Really ‘FDA Approved’?” update |
| General wellness | Low-risk products for general wellness use, such as relaxation or stress management and sleep management; FDA “does not intend to examine” them to determine whether they are devices | FDA general wellness policy |
| CE mark | Can be placed after a conformity assessment, which “usually involves an audit of the manufacturer’s quality system” | EMA medical devices CE mark page |
| FCC | Radio-frequency devices must be authorized before they can be marketed, imported or used in the United States | FCC equipment authorization page |
Neck posture and the vagus nerve
A 2025 cross-sectional study in Cureus, the Sureshbabu et al., 2025 text neck study, included 84 people aged 19 to 45. Forward head posture went with more sympathetic activity and less parasympathetic activity, measured through heart rate variability. The authors describe forward head posture as “associated with increased sympathetic and decreased parasympathetic modulation.” Heart rate variability is an indirect measure.
A 2025 paper in Frontiers in Neurology, Hauser et al., 2025 cervicovagopathy paper, proposes that forward-head phone use slowly stretches neck ligaments and affects the vagus nerve. The authors call this a hypothesis, drawn from a retrospective chart review of 234 patients, and say that resolving symptoms alongside improved vagus nerve measurements “will prove this hypothesis.” The authors also promote the cervical treatments they propose.
Our guide on whether neck tension or posture can affect the vagus nerve looks at what these early studies do and do not show.
The best evidence for auricular stimulation, according to Likar et al., 2023, is for chronic low back pain, chronic cervical syndrome, chronic abdominal pain and chronic migraine, plus some postoperative pain settings. Most studies in that review showed reduced analgesic or opioid intake.
For a closer look at one of those uses, read what studies show on vagus nerve stimulation for chronic back pain, including where the evidence is still limited.

Questions that settle your next step
- Is there numbness, tingling, weakness, or dropping held objects? If so, Cleveland Clinic says to call a provider.
- Does the pain travel down an arm or leg, or does it stay in the muscle? Travel points toward a nerve, according to Pain Management Specialists.
- Has the pain stopped you doing normal activities, or has it not improved after a few weeks? The NHS says to see a GP.
- Is any warning sign from the list above present? If so, follow the NHS advice to go to A&E or call 999.
What to write down before your appointment
Note where the pain is, the words you would use for it, what makes it worse, and whether it spreads or comes with numbness or weakness. Add the date it started. Bring the list to your visit. Our guide to low back pain red flags explains what to record.
