The same thing happened to me. About 2 years ago I had a seizure. 5 days later my eyes became sensitive to light where I needed to sit in the dark for 4 weeks. They put me on migrane medicine, which helped, but did not stop the light sensitivity. I have been tested for epilepsy, all eye medical conditions, MRI's, MRA's. They have determined I have high blood pressure which "spikes"on occassion. I have had every blood test in the world and all comes back fine. I do have hypothryroidism (for about 15 years). They have tested me for all types of rare diseases. At times I have fainted, with no warning except feeling dizzy. I have been to the best doctors and no one can find a cause. I am hoping someone has some advice or have experienced the same symptoms
