Karen,
I have been on the pred. taper, 3 times in the last two years. It did take away the extreme pain and stiffness so that I could get back to normal activities; which in turn made me very sore later.
When I am dong osmething- changing the oil in my car: I often have to stop for a bit, to let the muscles get used to the idea- like turning the nut on the oil pan.
Yes, I owudl take the taper again, but for me it was when I was nearly bed fast and wanting to die.
