I just have a intrasubstance mild partial thickness tear of the supraspinatus tendon and a slightly liquid in brush items. These are the problems which are scanned in mri from my left shoulder and then my doctor asked me to he in sling for few weeks and later I have gone through physiotherapy and asked me to do for about 6 months and it's 3 month from the day of injury and I still find like some kind of wetness and like something is falling inside shoulder like liquid and all and a slightly pain is there while performing physiotherapy. So is it a major problem and do I need to go to a other doctor?
