The spasms that I had, left me in so much pain, I was flat on back and trembling and shaking head to foot. I couldn't control the pain or the shaking. There is no way to describe it. I really wish that nobody had to go through this kind of agony. I pray that none of you do. I pray for resolution to all these back pain issues that leave us helpless. It is horrible to go through and horrible for a caretaker to witness. I pray each day for all of us. ginnie
