In 2008 I had a discectomy at L5-S1, and it didn't go very well. Last summer I had a fusion (TLIF I think it's called) at that same location. The disc was completely removed and replaced with a prosthetic, and I have permanent hardware there. The fusion got rid of the shooting pain down my legs, and "some" of the lower back pain. I would consider it somewhat successful.
However, recently I have developed a severe pain in my lower back, which starts below my fusion area and goes all the way to the end of my "tailbone". The pain is somewhat lessened if I remain perfectly still, but any movement of the area can be EXTREMELY painful. There is an overall constant dull pain, then regular severe sharp pain with movement.
I am scheduled for an MRI in 2 days, which of course I will be anxious for those results. I'm just wondering what the hell could possibly be going on there? Those bones are all supposed to be fused together. I had a rheumatologist who tested several months ago for sacroiliitis, but his conclusion was negative (although neither my wife nor I felt he was very diligent). Anyone else have something like this happen?
