Hi, I am currently 21 and I experience some unusual symptoms. This happens pretty rarely and randomly. However it has happened enough to where I am pretty concerned. I’ll be minding my own business (normally outside doing something) when all of a sudden my vision goes bad. As if someone shined a really bright light in my eyes and I cant really see. About an hour will go by when my head starts hurting like crazy and I start vomiting. Vomiting a LOT. Normally this lasts for what feels like forever before I finally fall asleep and try and recover. This has been happening randomly to me since I was in middle school. Is this considered a migrane? Has anyone here had similar experiences?
