Hi,sorry to know about it,Clinically,this symptom is same as problem that known as Thoracic Outlet Syndrome ,its' Symptoms include neck, shoulder, and arm pain, numbness, or impaired circulation to the extremities (causing discoloration). Often symptoms are reproduced when the arm is positioned above the shoulder or extended. Patients can have a wide spectrum of symptoms from mild and intermittent, to severe and constant. Pains can extend to the fingers and hands, causing weakness.
So I agree with DrNavneetMD,you should consult a doc again.
Good luck!
Hello Dear,
It seems that the trauma in cervical region is causing the shoulder pain and weakness.You should consult a physical therapist and do neck exercises and if he suggests you can take traction which may help you.
