Throwing a ball without warming up "tweaked" my right shoulder about a month ago.  Shortly afterwards, while doing push-ups, I felt something like a tearing in that shoulder.  Now I have pain with raising my arm, especially laterally, associated with weakness.  Being a physician, I looked up rotator cuff injury, and I seem to have every symptom and sign.  I was contemplating a visit with an orthopedic surgeon and probable surgery, but Nadine Terheggen, whose son had prolotherapy for an hip injury, told me to consult with Dr. Fields.
