yes, bebop, it sounds like nerve pain ... sciatic ... can you ask your Dr. to refer you to an orthopedic and then get some phys. therapy. it can help.
also, can you ask your dr. to change your pain med to something else, like norco, as it might help having less tylenol. then you can take extra tylenol in between. if he doesn't, your orthopedic should prescribe something appropriate for this severe pain.
good luck to you ... and heat helps as well as not walking around much till this is properly attended to. it's debilitating, the pain. some people need crutches, but a walker is good to use.
sorry you are suffering.
