If you guessed 3. Carpal tunnel syndrome, you are right!
Carpal tunnel syndrome is caused by compression of the median nerve as it travels through the wrist. Symptoms are pain, numbness, and tingling in the fingers, with aching and pain up the arm.
Carpal tunnel syndrome can cause weakness of the hand and loss of dexterity. Risk factors include obesity, repetitive wrist work, pregnancy, and family history.
Carpal tunnel syndrome can be diagnosed by physical examination, and can be confirmed with electrodiagnostic tests.
Carpal tunnel syndrome is treated by wearing wrist splints and steroid injections, but sometimes surgery is necessary to decompress the nerve.
Heart attacks can cause arm pain, but also typically have associated symptoms such as chest, neck or jaw pain. Sleeping on the arm can cause numbness, but it would be unusual to have symptoms on both sides. Arthritis can cause joint pain, but does not typically cause numbness or tingling.
