I have been suffering from shoulder rotation problems f outrom four months... Initially I was unable to move my hand due to pain.. After that I went to physiotherapy for almost two months and carried out  continuous physical exercises... And regular medicine..From then gentle movements made possible. Mean while there was a bulge (in shoulder to elbow part)...Which was hard and now smoothened... Finally I met a doctor who suggested me to undergo Manipulation under Anaesthesia ...Which I was really worried about. Need suggestion like Is MUA ok to go with or any risky or shall I need to look for an alternative treatment like surgery...
