What Causes Hand and Foot Pain?

Causes of hand pain may include certain disorders or infections, injury, vitamin B12 deficiency or nerve compression, states Healthgrades. Excessive walking, too much weight, arthritis, foot strain or stress fracture may cause foot pain, notes MedlinePlus. Gout, injury or nerve damage due to diabetes may also result in foot pain.

Injuries that can induce hand pain include dislocation of the finger, abrasion, ligament or muscle strain, crushing and laceration, according to Healthgrades. Bursitis; rheumatoid arthritis; tenosynovitis, a condition that involves inflammation of the tendon's sheaths; and tendonitis, which is inflammation of the tendons, are inflammatory causes of hand pain. Frostbite and age-related conditions, including osteoarthritis, may cause the pain.

Infection around the nail, a condition known as paronychia; cellulitis; septic arthritis and ganglion cyst may trigger hand pain, explains Healthgrades. Neurological causes of hand pain include neuroma, stroke, hypothyroidism, cervical spondylosis and injury to the spinal cord. Carpal tunnel syndrome, heavy metal poisoning, peripheral neuropathy, multiple sclerosis and a condition where the body destroys it's own healthy cells may also result in the pain.

Wearing shoes that don't fit properly, plantar fasciitis or warts, flat feet, corns or calluses may lead to foot pain, according to MedlinePlus. Other causes of foot pain include Morton's neuroma, a condition where nerves between toes thicken; foot deformity; broken bones; toes that resemble a claw; and bunions. Degenerative conditions such as aging may also induce the pain.
