It looks to me that either you are having a frozen shoulder
or an impingement syndrome
. I would suggest you to get MRI of shoulder to confirm this diagnosis. If injection of steroid
has not worked in your case other options are
, like hot water fomentation. And ROM exercises
2. Arthroscopic release, subacromial decompression (Key hole surgery)
You can post your reports to us also, i can offer you better advice.
