After wearing straps/bands, taking Ibuprofen and such I couldn't stand it anymore. I could barely lift my arm when I rolled over sleeping at night. Went to the Dr. and he gave me a cortisone shot. I too thought it was going to be painful as my Dad gets shots deep into his shoulder. This shot was not painful. It did take a day or two to feel the effects. I'm now about 2 months pain free. I wish I hadn't waited so long.
