Well I received my 3rd cortisone shot last Thursday and I'm happy to report, that I'm getting some relief. The first 2 didn't do anything, although my specialist said it was too early to tell. The next day(after the 3rd shot) I saw a marked improvement and now stretching and exercising isn't agony. I feel I can really start to get the movement back thank God.
So the 1st shot went in the front, the second one went through the back of the shoulder - he looked very confident with the 3rd one, which he put right through the top of the joint. I already have 80% movement back and I'm grateful for the pain relief. Thanks to all the members who've supported this thread.
