I would get a second opinion - I live in chronic pain
and have so for years. I had CT
and multiple Xrays done, which prove I have arthritis
and spodylolothesis - which is one on my L5 vertabrae didn't form correctly and then I got arthritis on it, because vertabrae shouldn't have movement the way it does with me. I have had some severe headaches, migraines and cluster type ones, but they almost completely stopped when I switched over to Lamictal from a SSRI.
