B.S.
I dealt with the pain in my shoulder for over 9 months, thinking that it meant a surgery that I couldn't have done. I could barely raise my arm and could not sleep at night. It was devastating. Finally gave in and went to the doctor. He sent me to a specialist immediately...the same day....made the appointment himself.
I had such good luck with the steroid injections. I did have to go back for a second one about a year later. Now it's been at least three and a half years since that second injection. I feel very fortunate. I didn't have physical therapy...but when I could move my arm and shoulder again, I used it normally. Didn't baby it.
A friend has had two surgeries on her shoulder and is still in pain. She's had all kinds of physical therapy. I'm sure it's different for everyone. But, I'd suggest giving it some time. Perhaps you'll be able to get some relief soon.
I know the surgery is best for others.
Good luck and God Bless....
