Thanks for the reply,not what I wanted to hear,I had back surgery 15 years ago to fuse together a broken tailbone,a month ago I stood up to 2 nurab legs and feet and butt.Chiropractor says it is in the L3 and 4 area where it was fused and he can fix it but living with this constant nurabness has got me down,some days I just sit and cry,thanks for quick reply,now I wish I hadnt asked.
