Good day, in 2017 i fell off a bicycle resulting in injury to my shoulder that gradually healed in a few months. since nov 2019 my shoulder has been hurting again with pain down my upper and lower arm, pain on lifting my arm above my head ?

Shoulder trauma: You need to consult with an orthopedic surgeon to make certain of the integrity of the rotator cuff. But if the joint is intact, next consider possibility of a problem in the brachial plexus (such as thoracic outlet syndrome). A vascular surgeon might be the next consultation. Ultrasound and EMG studies could help, but must be done properly by experienced clinicians.
