Your MRI report does not sound too exciting.... "without significant canal stenosis", "small rent", "small disc displacement", "no siginificant canal stenosis".... You'll probably get answers similar to what I got early in my career as a spine patient:
- "your films look too good for you to be reporting the kind of pain you are reporting" or,
- "I could pull 100 45 year-old men off the street who have NO symptoms and 1/2 of them would have an MRI that looks worse than yours.
Unfortunately, that does not help you. While both of those statements may seem true, even the parts of your spine that don't look too bad could be causing your problems.
Since you have a total hip replacement, the next joint in line for adjacent disease would be your SI joint. Has that been evaluated by someone who knows SI joint dysfunction?
How old is your MRI and does it predate an injury or substantial change in symptoms? Maybe it is out of date?
Good luck!
