Sadly - the best time I've had with no pain/almost no numbness, etc... was after spending almost a week lying flat in bed with a severe spinal headache after an LP - I got up only a couple of times a day to do "neccessities" and since I cant take anything stronger then a tylenol - my only pain relief was not moving.... I have never been so rested or felt better in the last 8 years then the week after that bed rest! Unfortunately thats no way to live - but it can happen!

(I'm now starting PT to try to help all symtoms - wer're hoping its going to help - but my body is not happy with it at all - giving it my all though....)
Maybe the mega-pain killers they give during surguires help? or the anesthesia somehows quiets the nerves?
