My back hurting soo bad I cant stand it. Does anyone know why this could be happening? I have had multiple mri's done from my neck all the way to my to my lower back. All they can find is a slightly bulging disk in L4 or L5 I think they said but nothing to be concerned about is what they said. I take percocet and tizanatine for pain. But this pain in my back when I wake up with everything numb from my waist down is unbearable and nothing helps. The doctor gives me NO answers at all! Please help.
