I got migraines too, after I had my son. I'd get them 2-3x a month. They were debilitating. Auras, nausea, pounding head, sensitive to light. I didn't even had medication to help them, I'd just suffer through. They'd be better after a nights sleep. I decided to check things in my diet that might be causing them. And there it was, caffeine and artificial sweeteners. I've been migraine free for 3 years. I also used to work for an ophthalmologist and optometrist. I had them check my eyes when i was having them, and all was well. Believe them. If they checked your pressure 4 times, looked at the back of your eyes with the light, and they said your eyes are healthy, believe them. Migraines are common too. Try not to worry too much.
