Hi There
I have had problems in the past with a bulging disc.that caused sciatic pain .I have been lucky and have only had two episodes where i had awful pain since in the last 20 years they only lasted maybe a week or so.yesterday i started getting a nerve pain in thetop of right buttock even just touching skin was painful on a scale of one to ten maybe a 6 so bearable .during the night i have now got pain from buttock down thigh into back of knee and tingling in the foot when i got up i am now unable to walk properly on that leg.The strange thing is there is no pain in back and the pain is no way as bad as i have had in the past my worry is i have a leg that is not working properly especially back of knee keeps giving way? is this sciatica?
