I'm having a little trouble distinguishing symptoms between SI joint pain and facet joint pain. My MRI shows that I have the beginnings of facet joint hypertrophy due to a left paracentral disc herniation at L5-S1. Slight retrolisthesis as well due to the disc dying. I have pain on the left side, but it seems to be right around where my "joint" is back there. When I sit down, I can make the pain almost go away by wading up a blanket and putting it where the pain is on that left side. It's always like things are uneven back there, which I guess would make sense because my pelvis is crooked.
I've read many posts, many articles, and I can't seem to figure out how to tell the difference between SI and facet joint pain. The symptoms seem so similar. My orthopedic surgeon and pain management doctor both want me to try facet joint injections, which I'll probably eventually do. Sometimes I wonder about the SI joint, though.
