Prednisone
"I have stiffness in lower back, pain in neck area, hips for many years but the pain is tolerable.  I also get periodic muscle stabs of pain followed by a twitch like when you fall asleep.  From time to time the pain would get bad and I would need to take pain medications.  Narcotics never worked but Toradol would work good BUT when I had a allergic reaction to the Toradol with hives and itching and went to the ER they gave me prednisone.  Within two days of taking the prednisone I had SO MUCH energy and was pain FREE.  I felt like I was 20 years old again.  I had ambition to get things done.  I felt SO good.  I felt like I discovered the fountain of youth.  Don't know if it is coincidence but I never had the pain until I contracted HSV."
