Welcome to NT.
Sorry you have these problems. I know it's not easy for you.
Even though it's small, it's an abormal finding, and can be causing you symptoms. Maybe consider a second opinion.
There was a radiologist around the forum that was willing to help with questions, but I haven't been on so much lately, I never saw any of his posts. Someone else here may remember and get that for you, and NT.
I would also suggest you keep a diary of your complaints, meds, activities, sleep patterns, any workarounds you're having to do, because of limited mobility and/or pain.
There are other things to treat symptoms with, besides pain pills. I did find there's always a trade, and to grade things I try, preferrably one thing at a time, as a positive or negative.
Keep asking questions. Understanding is half the battle.
