I had a calcified bursa on my right shoulder that had become so painful that, after six months of physical therapy, it was no better and I was scheduled for cortisone shots. I did not want them because of the immuno-suppressant tendency of cortisone. One night I had the impression to try a castor oil pack on it, just out of the blue. So I did. I wrapped my shoulder and underarm (after washing it) and left the pack on all night. In the morning the problem was 95% better. I did it four more nights and have not had the problem since. About five years now.
