Touch Sensitivity: Causes of Skin That Hurts to Touch

Types of touch sensitivity

Causes of touch sensitivity

Nerve damage (neuropathic causes)

Damaged nerves can misfire, so ordinary touch is processed as pain.

• Peripheral neuropathy: usually starts in both feet with burning, tingling, numbness and sensitivity to bedclothes. Diabetes is the most common cause; others include alcohol, vitamin B12 deficiency, kidney disease and some medicines.
• Shingles: burning, tingling or extreme skin sensitivity in a band on one side of the body, followed by a blistering rash 1 to 5 days later.
• Postherpetic neuralgia: pain and allodynia persisting more than 3 months after shingles, more common over age 60.
• Chemotherapy-induced neuropathy: sensitivity, tingling and numbness in the hands and feet after certain cancer drugs.
• Trapped nerves: such as meralgia paresthetica, which causes burning and sensitivity on the outer thigh.
• Spinal cord or brain problems: stroke, multiple sclerosis or spinal cord injury can cause central pain with allodynia.

Migraine

During a migraine, many people develop cutaneous allodynia: brushing hair, wearing glasses, earrings or a ponytail becomes painful. It can spread to the arms. Its presence suggests treatment should be taken early in an attack, before sensitivity sets in.

Fibromyalgia and central sensitization

Fibromyalgia causes widespread pain, tenderness to touch, fatigue, poor sleep and concentration problems. The nervous system amplifies pain signals (central sensitization). It is common, especially in women.

Complex regional pain syndrome

CRPS usually follows an injury or surgery to a limb. Severe burning pain, extreme sensitivity to touch, swelling, and color and temperature changes develop out of proportion to the original injury. Early treatment with physiotherapy improves outcomes.

Skin causes

• sunburn
• eczema or dermatitis flares
• skin infections such as cellulitis
• after skin injury, burns or surgery, as nerves regrow

Infections and illness

Flu, COVID-19 and other viral illnesses often make the skin and muscles feel sore to touch, especially with fever. It settles as the illness passes.

Sensory processing differences

Children and adults with autism, ADHD or sensory processing disorder may find certain textures, clothing seams, light touch or hugs overwhelming. This is a difference in how the brain filters sensory input rather than pain from damage. Occupational therapy can help.

Other causes

• vitamin B12 deficiency
• withdrawal from opioids or alcohol
• anxiety and lack of sleep, which lower pain thresholds

How doctors find the cause

Your doctor will ask where the sensitivity is, how it started, what it feels like, whether there is a rash, and about diabetes, alcohol, medicines and chemotherapy. They will test light touch, pinprick, vibration, temperature, reflexes and strength, and map the affected area. A dermatomal band on one side suggests shingles; both feet suggests neuropathy.

Tests may include:

• blood tests: blood sugar or HbA1c, B12, thyroid, kidney and liver function
• nerve conduction studies and EMG
• MRI of the spine or brain if a central cause is suspected
• skin biopsy for small fiber neuropathy

Treatment

Treat the cause

Control blood sugar, correct B12 deficiency, stop toxic medicines where possible, and start antiviral medicine early for shingles.

Medicines for nerve pain

• Amitriptyline, duloxetine, pregabalin or gabapentin are first-line options for neuropathic pain. They take a few weeks to work.
• Lidocaine patches or cream numb sensitive areas.
• Capsaicin cream or high-dose patches deplete pain signals over time.
• Standard pain relievers such as acetaminophen and ibuprofen help little for nerve pain.

Desensitization and therapy

• Graded exposure to different textures, guided by a physiotherapist or occupational therapist, retrains the nervous system.
• Exercise, good sleep and stress reduction lower central sensitization.
• Cognitive behavioral therapy helps with chronic pain.

Practical tips

• Wear soft clothing without rough seams; cut out labels.
• Use a bed cradle to keep sheets off sensitive feet.
• Cool compresses can soothe burning skin.
• Avoid very hot baths if you have numbness, to prevent burns.

Frequently asked questions

Why does my skin hurt to touch with no rash?

Common causes include early shingles before the rash appears, nerve damage from diabetes or other causes, migraine, fibromyalgia, and viral illnesses with fever. If the pain is in a band on one side of the body, see a doctor quickly, as shingles treatment works best early.

What is allodynia?

Allodynia is pain caused by something that is normally not painful, such as clothing, a light touch or a breeze. It happens when nerves or the brain's pain-processing system become oversensitive, as in neuropathy, shingles, migraine, fibromyalgia and complex regional pain syndrome.

Can anxiety cause skin sensitivity?

Anxiety and poor sleep can lower your pain threshold and make sensations feel more intense. They can also cause tingling. However, skin sensitivity should not be blamed on anxiety without considering physical causes, especially if it is in a specific area or comes with numbness.

Why does my skin hurt when I have a fever?

During infections, the immune system releases inflammatory chemicals that sensitize nerves throughout the body. Skin and muscles can feel sore and tender to the touch. This usually resolves as the fever and illness pass.

How is touch sensitivity treated?

Treatment targets the cause, such as controlling diabetes or treating shingles early. Nerve pain medicines like duloxetine, pregabalin or amitriptyline, topical lidocaine or capsaicin, and desensitization therapy with a physiotherapist or occupational therapist can reduce sensitivity.
