How much does back surgery for a pinched nerve cost?

hi, before you pay for surgery, why don't you try exercise's? i have just found out i have the same a pinched nerve, and its making my buttocks and back of legs burn and tingle, but my doctor told me to lay flat on your back on a hard surface ie.. floor, then pull each knee, 1 at a time up to your chin as high as you can each 1 10x 3 x aday for 3 wks, i have now been doing it for 2 wks and i feel alot better, it come back a little today, but my doctor said it moves the nerve back across, if you have any exercises etc would love to hear about them of you, many thanks James
