yes I have had lower back problems (L4 AND L5 spinal area) since the other mercury symtoms started to get worse about a year ago ,I had xrays of the spine area done and the doctor told me that it was not a slipped disc (thank god) there was a small amount of compression in that area but nothing serious ,started to see a chiropractor and have had much success with him ,also started doing much better after having amalgam removed,the combination of the two have helped alot MIKE
