Why Does My Hand Hurt?
The honest verdict
This is usually not an allergy
Hand pain is rarely if ever caused by an allergy. Allergic reactions can cause hives or swelling of the hands in people with contact or food allergies — but the pain itself is not the primary feature. Hand pain as a chief complaint is overwhelmingly musculoskeletal, neurological, or arthritic in origin, and the workup is clinical and imaging-based, not allergy-based.
This is a general research summary, not a diagnosis. It can't tell you what's causing your symptom — a clinician can.

When hand pain 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
A hand or fingers that are suddenly cold, pale, or blue (cyanotic) after an injury, dislocation, or without an obvious cause — call 911 immediately (possible arterial injury or acute vascular occlusion).
Call 911 or go to the ER now
- Emergency
Severe hand pain with significant swelling, fever, redness spreading up the forearm, or inability to straighten a finger — seek emergency care immediately (possible severe infection including flexor tenosynovitis).
Call 911 or go to the ER now
- Emergency
Hand pain with sudden loss of grip strength, inability to move fingers, or new numbness after a fall or crush injury — seek emergency evaluation for fracture or nerve injury.
Call 911 or go to the ER now
- Urgent
Hand pain with skin discoloration and swelling after an animal or human bite, or a puncture wound near a joint — seek urgent care the same day; bite-related infections can spread rapidly.
Get seen today — urgent care or same-day visit
- See a doctor
Progressive bilateral hand pain and stiffness with morning stiffness lasting over an hour, or swollen, warm joints in both hands — see a clinician for an autoimmune and inflammatory arthritis workup.
Book a routine visit with a clinician
When in doubt, err toward getting seen. These tiers are a general guide, not a substitute for a clinician's judgment about your specific situation.
Key facts
Carpal tunnel syndrome — compression of the median nerve at the wrist — is among the most common causes of hand pain and numbness, especially in people with repetitive hand use.
Flexor tenosynovitis from a bite or puncture wound near a finger joint is a hand surgery emergency — the tendon can be destroyed within hours without surgical irrigation.
Rheumatoid arthritis most commonly begins in the small joints of the hands and feet and requires disease-modifying antirheumatic drugs to prevent joint damage.
What's causing it
The same symptom can come from very different places. Here are the usual suspects for Hand — fingers, palm, wrist, or diffuse, tagged by mechanism and how common each one is — so you can see where an allergy actually fits.
Carpal tunnel syndrome
Compression of the median nerve at the wrist produces pain, numbness, and tingling in the thumb, index, middle, and part of the ring finger. Symptoms are often worse at night or with repetitive hand use. A clinician can diagnose this with a physical exam and nerve conduction studies.
Osteoarthritis
Wear-and-tear arthritis commonly affects the small joints of the fingers and the base of the thumb (carpometacarpal joint), causing aching pain, stiffness, and bony enlargement. It is more common with age and is diagnosed by exam and X-ray.
Tendinopathy and trigger finger
Overuse or repetitive motion can inflame tendons in the hand and wrist (including de Quervain's tenosynovitis at the thumb side of the wrist). Trigger finger occurs when a tendon sheath becomes inflamed, causing a finger to lock or catch when bent. Both respond to specific conservative treatments.
Inflammatory arthritis (rheumatoid, psoriatic)
Rheumatoid arthritis and psoriatic arthritis frequently affect the small joints of the hands, causing pain, morning stiffness lasting more than an hour, warmth, and swelling in a symmetric or characteristic pattern. These autoimmune conditions require specialist care and disease-modifying treatment.
Peripheral neuropathy
Diabetes, vitamin B12 deficiency, and other systemic conditions causing peripheral neuropathy can produce burning pain, numbness, or tingling in the hands — often affecting both sides and worsening at night. Treatment targets the underlying cause.
Hand or finger infection (felon, flexor tenosynovitis)
Infections in the finger pulp (felon) or along the tendon sheath (flexor tenosynovitis — often from a puncture wound or bite) can cause severe, rapidly worsening pain with swelling, redness, and warmth. Flexor tenosynovitis is a hand surgery emergency — it can destroy the tendon within hours if untreated.
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.
Hand pain is not caused by allergies. Contact dermatitis can make hands red and itchy — particularly from nickel, latex, or cleaning products — but the primary symptom is skin irritation and itch, not deep joint or nerve pain. If your hands hurt rather than itch, the cause is musculoskeletal, neurological, or arthritic, and a clinician is the right starting point.
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
Rule out an emergency first
A cold, pulseless, or rapidly infected hand requires emergency care — not rest or self-treatment. If any of the emergency signs above apply, seek care before trying any home remedies.
- 2
Rest and activity modification for musculoskeletal causes
For typical overuse or strain-related hand pain, reducing the aggravating activity and using a splint (for carpal tunnel or trigger finger) can reduce symptoms while awaiting medical evaluation.
- 3
See a clinician for an accurate diagnosis
Hand pain has many distinct causes with very different treatments. An accurate diagnosis — by physical exam, X-ray, ultrasound, or nerve conduction studies — is essential before starting any treatment, including physical therapy, injection, or medication.
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
Seek emergency care for a cold or pulseless hand, rapidly worsening infection, or significant hand trauma. Seek urgent care for a bite or puncture wound near a hand joint. See a clinician for persistent hand pain, pain with morning stiffness and swollen joints, or any new numbness or weakness in the hand.
Frequently Asked Questions
Allergies very rarely cause hand pain. Contact dermatitis from allergens like nickel, latex, or fragrances can make the skin of the hands itchy, red, and inflamed — which may be mildly uncomfortable — but deep joint pain, tendon pain, or nerve pain in the hand is not an allergic symptom. If your hands hurt rather than itch or swell, the likely cause is musculoskeletal, arthritic, or neurological.
Carpal tunnel syndrome typically produces numbness, tingling, and sometimes pain in the thumb, index, middle, and part of the ring finger — the area supplied by the median nerve. Symptoms are often worse at night and may wake you from sleep. Shaking the hand often temporarily relieves symptoms. Over time, grip strength can weaken. A clinician can confirm the diagnosis with a nerve conduction study and electromyography.
Arthritic hand pain typically involves the joints — the knuckles or the base of the thumb — and is often accompanied by stiffness, especially in the morning. Osteoarthritis causes bony enlargement and is more common with age; rheumatoid arthritis causes warm, swollen joints, often symmetric across both hands, with prolonged morning stiffness. A clinician can distinguish these with an exam, blood tests, and X-rays.
Flexor tenosynovitis is an infection of the tendon sheath along a finger, usually following a puncture wound or bite. It causes severe pain along the entire length of the affected finger, swelling, and inability to straighten the finger. It is a hand surgery emergency because the tendon sheath infection can destroy the tendon within hours, causing permanent loss of finger function. Same-day surgical evaluation and irrigation is typically required.
Go to the ER for hand pain if the hand is cold, pale, or pulseless after injury (possible arterial injury); if there is severe swelling, fever, and a finger that cannot straighten after a bite or puncture (flexor tenosynovitis); or if significant trauma has caused deformity or inability to move the hand. Urgent care is appropriate for bite wounds near finger joints. Aching joint pain without these features can be seen by a primary care clinician or orthopedist on a scheduled basis.
