I was hit from behind in a car accident while giving a stoping hand signal. At the time of impact because of how my shoulder was located between the door frame the ligaments in my shoulder were torn. After about a month of severe pain i went to the doctor and was given medication as the blood from the ligament being torn went into the arm and shoulder muscles and had become infected. The accident was in Feburary and the medication was taken throughout April. My doctor said that after the medication everything should be fine, however we are in May now and i still have much pain and limited use of my right hand. Is some form of physical therapy needed and if so what can i do to start this process.
