I've been seeing a neurologist for years for migraine, and am on several meds like topamax, wellbutrin, provigil (fatigue to the point where I can't keep my eyes open while driving), and rescue meds. Along with migraine is persistent, ridiculous, and inexplicable tinnitus which we gave up trying to resolve. I recently had periodic blood work done and came back with low vitamin D (<15), low B12 (low 200s), low hemoglobin (<11.5)-none which seemed earth-shattering to me.
