Why Does My Skin Hurt?
The honest verdict
This is usually not an allergy
Painful skin is rarely caused by an allergy. Allergic skin reactions typically cause itching, redness, swelling, or hives — not pain. When skin hurts, the cause is more often nerve-related (shingles, neuropathy), infectious (cellulitis, an abscess), or inflammatory (psoriasis, vasculitis). If the pain is accompanied by a blistering rash on one side of the body, shingles is a strong possibility. If the skin is red, warm, and tender to the touch, especially with fever, cellulitis may be present. Pain without a visible rash may signal a nerve condition like diabetic neuropathy or fibromyalgia.

When painful skin is an emergency
Most of the time this can be handled calmly. But a few signs mean you shouldn't wait. Match what you're seeing to the right level of care below.
If any emergency sign below is present, call 911 or go to the ER now.
- Emergency
Fast-spreading redness, warmth, swelling, or red streaking from the painful area, especially with fever or chills — go to the ER (possible spreading cellulitis or sepsis).
Call 911 or go to the ER now
- Emergency
Painful skin with a dark, black, or purple patch that feels cool or numb — call 911 (possible necrotizing fasciitis, a rare but life-threatening flesh-eating infection).
Call 911 or go to the ER now
- Urgent
Painful blistering rash on one side of the face, especially near the eye or nose — seek urgent care or ER (shingles near the eye can threaten vision).
Get seen today — urgent care or same-day visit
- See a doctor
Painful skin after a tick bite, especially with a bullseye rash or flu-like symptoms — see a clinician promptly (possible Lyme disease).
Book a routine visit with a clinician
- See a doctor
Persistent or worsening skin pain without a clear cause, or pain accompanied by unexplained weight loss, fatigue, or night sweats — see a clinician (possible underlying systemic condition).

Key facts
Shingles affects about 1 in 3 people in the United States during their lifetime, and the risk increases with age, especially after 50.
Cellulitis sends about 14 million people to the doctor each year in the U.S., and it is one of the most common skin infections requiring hospitalization.
Peripheral neuropathy affects approximately 20 million people in the U.S., with diabetes being the most common cause.

What's causing it
The same symptom can come from very different places. Here are the usual suspects for Skin — the body's largest organ, covering the entire external surface. Pain can be localized to a specific area (e.g., a patch on the torso, a limb, the face) or widespread., tagged by mechanism and how common each one is — so you can see where an allergy actually fits.
Shingles (herpes zoster)
Shingles is a reactivation of the chickenpox virus, causing a painful, blistering rash that typically appears on one side of the torso or face. The pain can be burning, stabbing, or throbbing and often precedes the rash by a few days. It is most common in adults over 50 and those with weakened immune systems. Antiviral medications work best when started within 72 hours of the rash appearing.
Cellulitis or skin abscess
Bacterial infections of the deeper layers of the skin cause redness, swelling, warmth, and tenderness in a localized area. Cellulitis often follows a cut, scrape, or insect bite. Fever, chills, and red streaking along the skin are signs the infection is spreading and require urgent medical attention. Treatment involves antibiotics.
Peripheral neuropathy
Nerve damage — most often from diabetes, but also from vitamin deficiencies, alcohol use, or chemotherapy — can cause burning, stinging, or shooting pain in the skin, especially in the hands and feet. The skin may look normal. Numbness or tingling often accompanies the pain. A clinician can diagnose the underlying cause and recommend treatments like nerve pain medications or topical agents.
Postherpetic neuralgia
After a shingles outbreak, some people experience persistent nerve pain in the same area for months or even years. The skin may be exquisitely sensitive to light touch (allodynia) — even clothing brushing against it can cause pain. This condition is more common in older adults and can be treated with nerve pain medications, lidocaine patches, or capsaicin cream.
Inflammatory skin conditions (psoriasis, lichen planus, vasculitis)
Some inflammatory skin diseases can cause pain alongside the more typical itch. Psoriasis can cause painful, cracked plaques on the hands and feet. Lichen planus can cause painful purple bumps on the skin and inside the mouth. Vasculitis (inflamed blood vessels) can cause painful, tender spots or ulcers on the skin, often on the lower legs. These conditions require a dermatologist for diagnosis and treatment.
Contact dermatitis (irritant or allergic)
Contact dermatitis typically causes itching, but severe reactions — especially to strong irritants like acids, alkalis, or certain plants (e.g., fire coral, giant hogweed) — can cause burning pain and blistering. Allergic contact dermatitis (e.g., to poison ivy, nickel, or fragrance) is more likely to itch than hurt. Pain as the primary symptom is unusual for a contact reaction.
Is this an allergy? Usually, no
It's a common assumption, so it's worth being clear about — and pointing you toward what's more likely going on.
Painful skin is usually not an allergy. Allergic skin reactions — whether from food, medication, or contact with an allergen — typically cause itching, redness, swelling, or hives, not pain. If the skin hurts rather than itches, the cause is far more likely to be nerve-related (shingles, neuropathy), infectious (cellulitis), or inflammatory (psoriasis, vasculitis). In rare cases, a severe allergic contact dermatitis to a potent irritant can cause burning pain, but this is the exception. If you have skin pain without significant itching, an allergy is unlikely to be the cause.
Because an allergy is unlikely to be the driver, the most useful next step is a clinician who can look at the actual cause — not an allergy test.
Relief you can try at home
If your symptom is mild and you have no red-flag signs, these gentle steps often help. They soothe — they don't replace figuring out the cause.
- 1
Protect the painful area
If the skin is painful to the touch, avoid tight clothing, harsh soaps, and direct pressure. Loose, soft fabrics like cotton can reduce irritation. For shingles, keep the rash clean and dry to prevent secondary bacterial infection.
- 2
Apply cool compresses
For pain from shingles, cellulitis (only if not worsening), or inflammatory skin conditions, a cool, damp cloth applied for 15-20 minutes can soothe the area. Do not apply ice directly to broken skin.
- 3
Use over-the-counter pain relievers
Acetaminophen or ibuprofen can help manage mild to moderate skin pain from shingles, neuropathy, or inflammatory conditions. Always follow label directions. Topical lidocaine or capsaicin cream may help for nerve-related pain.
- 4
See a clinician for prescription treatment
Shingles requires antiviral medication (best within 72 hours of rash onset). Cellulitis needs antibiotics. Nerve pain often responds to prescription medications like gabapentin, pregabalin, or tricyclic antidepressants. A clinician can determine the right treatment for the specific cause.
Stop any step that makes things worse. If the symptom isn't easing within a few days, check in with a clinician.
When to see a doctor
See a clinician promptly if you have painful skin with a blistering rash (possible shingles), red and warm skin (possible cellulitis), or pain after a tick bite. Seek emergency care for fast-spreading redness with fever, dark or black patches of skin, or pain near the eye with a rash. If the pain is persistent, unexplained, or accompanied by numbness, tingling, or weakness, a nerve condition may be the cause and requires evaluation. Painful skin without a visible rash should not be ignored — it may signal an underlying medical condition like diabetic neuropathy or fibromyalgia.
❓Frequently Asked Questions
It is very rare for an allergic reaction to cause skin pain as the primary symptom. Allergic reactions typically cause itching, hives, redness, and swelling. Pain — especially burning, stinging, or shooting pain — points to a different mechanism, such as nerve irritation (shingles, neuropathy) or infection (cellulitis). If you have painful skin without significant itching, an allergy is unlikely to be the cause.
Shingles pain is often described as burning, stabbing, throbbing, or electric-shock-like. It typically affects a strip of skin on one side of the body — the torso is most common, but it can occur on the face, arm, or leg. The pain often begins a few days before a blistering rash appears. The skin may be extremely sensitive to light touch (allodynia). Shingles requires antiviral treatment, so see a clinician promptly if you suspect it.
Painful skin is an emergency if it is accompanied by fast-spreading redness, warmth, swelling, or red streaking with fever or chills (possible spreading cellulitis or sepsis). A dark, black, or purple patch of painful skin that feels cool or numb is a medical emergency (possible necrotizing fasciitis). Painful skin near the eye with a blistering rash needs urgent evaluation to protect vision.
Skin pain without a visible rash is often nerve-related. Common causes include peripheral neuropathy (from diabetes, vitamin B deficiency, or chemotherapy), fibromyalgia (widespread pain with tender points), or early shingles (pain precedes the rash by a few days). Less common causes include complex regional pain syndrome or small fiber neuropathy. A clinician can help identify the underlying cause through history, physical exam, and sometimes nerve tests.
Stress does not directly cause skin pain, but it can worsen conditions that cause pain. Stress can trigger shingles outbreaks, flare psoriasis, and increase the perception of pain in conditions like fibromyalgia. Stress also raises inflammation in the body, which can aggravate inflammatory skin conditions. Managing stress through relaxation techniques, exercise, and adequate sleep may help reduce symptom severity.
Yes — painful skin, especially in the hands and feet, can be a sign of diabetic peripheral neuropathy. Chronically high blood sugar damages small nerve fibers, causing burning, stinging, or shooting pain, often accompanied by numbness or tingling. The skin may look completely normal. Diabetes can also increase the risk of skin infections like cellulitis. If you have unexplained skin pain and risk factors for diabetes, see a clinician for evaluation.
