I saw neurologist last week re: thunderclap h/a March 14 followed by daily headaches (with vision issues) for a month. I only take otc stuff for h/a rated a 5 or greater on pain scale to avoid rebound h/a. Found out the "regular" brain MRI wasn't sufficient, I need to have a brain MRI angiogram. A MRI machine with special software, it can see small to mod size aneurysm better than regular MRI. I had no idea. So danimartinez- I think you should ask for that since migraines are new to you. He also had me start Vit B2(riboflavin), I have felt h/a's start but then they fade. I think its helping. He also ordered Ubrelvy but its expensive, hasn't been filled yet. Good luck
