I ve been having back pain for bout a week now. It started on the right between the hip and kidney. It spreads depending on if I ve been sitting etc... I ve been running a low grade fever off and on and have been a little nauseous. I also have endometriosis. Its been getting much worse than its ever been since the back pain started. I ve been feeling popping in both the back and just recently the front. I felt a sort of ripping feeling also just today in the front. Right around my belly button has been stinging or burning I think is the best way to describe it. A little throbbing too with an ache. My right leg has been pinching from the back pain, going a little numb from time to time. Sometimes I can t walk at all from the back pain and sudden stabbing pains in the front right over where my female organs are. I m not sure if its just a muscle strain in the back and having to baby it is messing with the endo, or if its something I should really be concerned about. Heat works sometimes cold not so much. Pain killers hven t been helping at all, it wasn t until I took 3 Excedrin and drank a whole can of Mt Dew that I got any relief.
