I have for a number of years suffered pain down the front side of my right thigh (vastus lateralus?} with discomfort in the side of that knee, right lower leg and pins and needles in my right heel. I also have lower back discomfort. I have seen physiotherapists, including spinal specialist physios. An MRI scan indicated a slipped disc at L4/L5 and a bulging disc at L5/S1, but a neurosurgeon subsequently indicated that I have a healthy back (for my age - 76). Is acupuncture a viable and appropriate treatment to resolve this problem long term, how much is treatment and would a single session be sufficient? Kind regards
