I had shoulder spasm about a  month ago. But few days back the pain was back again. I did some streching exercises and after fews days it worsened. I was not able to lift my arm.  I did my MRI and consulted a orthopedist. As per MRI and doctor, I have supraspinatus tendinitis. Doctor says it is a minor injury and not much to worry about. Still I have fears and it feels quite irritating that I am able to raise my arm. Doctor has advised Tendocare medicine for 3 weeks. I wanted to know, how long will it take to cure? Will it be cured permanently or the pain may rise again in future? Please help to guide. Thanks in advance.
