I too am new this site & I am also having a sharp pain in my right buttock, up to my lower back & down my leg all the ways to the toes on my right leg. It's getting so I can't walk anymore & sitting, standing, walking are all just too much for me. I've been under a Chiropractors care but that doesn't seem to be helping. I have had CT scans done & no one can seem to find the problem. There are times when my back gives out & I have to walk slumped over. I have many other medical maladies that I am dealing with but even though I've never injured myself that I know of. It just started one day & has gotten consistently worse.  I've had this problem for years no one knows where it came from or what to do with it.If you find out anything would you be so kind as to let me know. Thank you...Diane Shore<br>
