4 years ago I had an onset that started with an ocular migraine. From then on anything stressful triggers a migraine. Over the years it has progressed blenned vision bad fatigue excercise intolerance slowed speech digestive issues etc. I have lesions on my brain from an mri. Had so many blood tests all fine including lymes. Been to so many different doctors now i am told it may be Dysautonomia. The thing is they want another 10 expensive blood tests and a tilt table test. I dont pass out. Your thoughts?
