@arlenejc I'll keep that in mind for the future, but this is a cyst that could be pressing against a nerve and causing damage. I want to know if that's the case. @summertime4 Yes! And since my doctor said I might eventually need epidural injections, and since neurologists apparently do those, I'm really considering going to one for at least a consult.

I did some more research and apparently these cysts are asymptomatic, but occasionally can be symptomatic and cause exactly the pain I'm having. I'd hate to just ignore this and find out a few years from now that I have permanent nerve damage. I can ignore pain, to some degree, but I'm not going to be able to ignore loss of function.
