bursitis
"I had elbow bursitis so bad, I could not sleep, move my arm. Missed work etc. Tried Advil, naproxen and tylenol and codeine.  Prednisone is the only thing that works and started working within 6 hours.  Took it for 7 days and my arm felt so much better. After I went off, it slowly came back but not quite as bad.  Took it for another 7 days and it healed 90 percent."
