hi rjay
we spoke before (wendy) i can relate to the pins and needles in arms and hands and numbness which when i asked my consultant said it is all normal with deg disc l4/l5 l5/s1. and as for the funny feeling in your feet my sister is in to reflexology and i have really worn and sore bit in the middle of the underneath of my feet and she says the middle represents the spine and mine is sore on the bit representing the lower but also the upper spine caused by tension! so yes this can make your feet feel funny as i have only had problem since my back!!!
hope your op goes ok and keep in touch as mine has now been put back to july am so pissed off at mo as i am banking on this being a cure think if it doesn't will be suicidal X X
good luck x
wendy
