Any number of things. Strenuous exercise, a fever, fear, stress, anxiety, certain medications, and street drugs can lead to sinus tachycardia. It can also be triggered by anemia, an overactive thyroid, or damage from a heart attack or heart failure.
carpal tunnel syndrome. a common disorder of the wrist and hand characterized by pain, tingling, and muscular weakness, caused by pressure on the median nerve in the wrist area and often associated with trauma, rheumatoid arthritis, or edema of pregnancy.
[edit on Wikidata] In the human body, the carpal tunnel or carpal canal is the passageway on the palmar side of the wrist that connects the forearm to the hand. The tunnel is bounded by the bones of the wrist and flexor retinaculum from connective tissue. Normally several tendons from the flexor group of forearm muscles and the median nerve pass through it. There are described cases of variable median artery occurrence.
