@koesch01 I'm sorry this happened to you. Is this a recent change that happened right after the epidural injection or has this been more of a long term problem? What I might suggest is a work up with a spine specialist and a physical therapy evaluation. There may be a different reason for the pain that can be addressed with treatment. I have made mistakes before thinking a pain was caused by sinus problems and in fact, it was a tooth. That kept me from seeing my dentist because I thought I knew the answer. It gets tricky when there are overlapping symptoms caused by different problems. Nerve problems can be tricky too and seem like spine problems when they are not or they can be spine problems that cause pain elsewhere in the body.
