I am male aged 38 height 5'8" weight 74Kgs. A month back while working out in the gym i think i pulled a muscle in my left arm. I stopped working out immediately and went to a local GP who confirmed a muscle pull. He gave me some in house pills which took away the pain after 3 days. It has been more then 3 weeks now the pain from the forearm is gone, but when i raise my arm above head i feel a pulling sensation and a visible vein running through my upper arm starting from the elbow joint all the way to my under arm. also while my arm is raised a little pulled sensation can be felt in the forearm aswell. The vein kind of pops out when the arm is raised and it feels like hardened vein. Please suggest best possible approach of treatment.
