hi folks ive done my back in on the lower left side. i can hardly feckin walk and get a sharp pain not unlike a bad cramp that drops me like a stone one minute i'm trying to walk the next i'm on the deck. in a fair bit of pain . the doc has given me pain killers and anti inflamatories and says the muscle may be pressing on a nerve. i was wondering if any of you have had the same and how did it work out.
