Asking this question because I noticed the worst symptoms fibro gives me deals with headache and neurological disturbance (many unexplained things). After having a highly sensitive MRI (normal results with a white matter intensity the neuro believes is not a real lesion) and being assigned amitriptyline, I noticed an improvement in the headache/head pain. Initially, it got in the way of me doing exercises, like plank pikes and leg lifts etc. So I stopped and started letting the medication work and went back to walking. Now today, I noticed that my headache is back (with weeks prior of migraine-like symptoms phantom smells and visual distubances) and brought on by brisk walking, like an exertional headache. Not sure if something triggered the headache/migraine but just a night ago I went to bed early because I had intense pain over my right eye like headache/migraine. Does anyone find that their fibro flares in different ways throughout the body? It feels like I have a permanent underlying headache/migraine that can flip on for reasons I am still trying to identify.
