I've had lower back pain for years and visited chiropractor etc. with varying degrees of success. The stiffness and ache I pretty much just accept but more recently (in last two months) I've started getting a tingling, sort of pins and needles but not that strong in my feet and lower parts of my legs - worse in the evening when sitting - in fact I just can sit and relax because of it. Just in the last couple of weeks I've noticed it in my hands mostly pinky + ring finger. Its now driving my nuts and I' scaring myself by reading what this could be a sign of. By the time I go to bed again, it feels like this buzzing, trembling feeling is in my back and my heart too!!!
