Common problems of pain in the left hand can indicate injury, as in a fracture; nerve problems, as in carpel tunnel syndrome; or inflammation, as in tendinitis, according to WebMD. Although these conditions all exhibit hand pain, they also have unique complementary markers.
A fracture, in any bone of the hand, could result in loss of movement of the fingers, according to WebMD. The injured finger may also swell. Arthritis.org explains that tendinitis is caused by inflammation of tendons, which can happen in any joints of the fingers. Meanwhile, carpal tunnel syndrome is caused by a nerve that lies in the arm, under a muscle, according to Patient.co.uk. The muscle can put pressure on the nerve and result in pain or numbness of the hand.
