So the short story is that I am having severe lower back pain that makes me fall suddenly to my knees. I can feel it it my groin and thighs. There are no remarkable finding on an x-ray. My PCM says they are just muscle spasms. I have had back pain for years, but for the past 2 weeks it has been severe and constant. Like I said, it takes me down. Could it really just be muscle spasms? They want me to go to physical therapy before they will order an MRI, but they don't say how long they will make me go for. The ER treated me as though I was there seeking drugs and didn't even do any imaging and sent me home with tylenol and flexeril so that did absolutely nothing for me. Does this sound like muscle spasms? Should I push harder for further imaging?
