Hello Actually I'm a national level badminton player from Delhi. Two months earlier, while doing exercise (chin ups on horizontal rod) in gym, I felt pain in my LEFT shoulder bone. First I thought it's a muscle spasm or some condition that had lead to injury in my MUSCLE, so I took an off from gyming and all kind exercises for 2 MONTHS. Though the pain has reduced a lot but I keep on feeling some sensation of little pain when I sleep turning on my LEFT side. It feels like something is pinching in my collar bone. So I think it's not a muscle injury because it has not recovered even after two months rest period. I want to start exercise because not doing it is effecting my body & sports carrier too, before that I want to confirm that would my shoulder be OK and it won't be a problem if I start exercise again. For that purpose, should I go through the NORMAL MRI or CONTRAST MRI scan? Or any other precious suggestion from you? Please help me as soon as possible. Thank you.
