The pain may be felt all along the arm. 2  Carpal tunnel syndrome: carpal tunnel is a passage in the wrist. It is through this tunnel the medial nerve and the tendons of the forearm muscles pass and attach to the finger joints. Carpal tunnel syndrome occurs when the medial nerve is pinched in the carpel tunnel. It causes burning pain in forearm and wrist.
