Hi........don t have a lot of trouble with my back during the day with walking, sitting etc, sometimes when standing, but when I lay in bed of a night, and any movement a sharp electric severe pain shorts through my lower back and each time I move it grabs my back...once I go off to sleep for a couple of hours and wake up and move on bed, I don t get the pain and no more sharp severe pain until the next night....it happens the first time I lay down each night.....
