Extreme pain when it is activated by small misstep on carpet, standing at the wrong angle. At that time there is pain close to a 9 on the 1-10 scale, mostly like a U around the coccyx, thru the glutes and down the center of my thighs. I am, currently, sitting upright on a soft surface with ice on the low back/coccyx area with a pain of about 2. Walking will activate this pain incredibly...it is a bit of an electrical and sharp/nauseating feeling. I have taken 3 325 hydros and freezing it to death (yeah, I know). I am to receive shots at the point I guess, of certain facets tomorrow. I have experienced this one time before. My question: is it possible to have a certain disc go back and forth from being herniated...because I had all pictures taken just 2 weeks ago. Yes, I have A LOT of bulging in and out... arthritis here and there Any insight?
