Hi i am new here. First, my personal history, it all started when i was in high school (14yrs old) freshman. I seldom wore my eyeglasses, at those times, and then started to wear frequently because my eye doctor stated my monthly nausea was due to my lack of not wearing eye glasses. But later he was wrong. Then later on, in my sophmore year, my nurse was looking at my track record and advise me to see a docotor. And i told him, and he declared it was a migraine headache. I never kept track when it happens, until when i was in college, and it happens when the season started to change. so it will be 4 times in one year. But suddenly this year , i recognized that it appears twice in one season . Sometimes, when i get carried away, saying to myself since it happens once a new season, i saw the trigger, then ignored it. That is when i realized it can happen twice. So there you have it.
