Hi, I am a 22 y/o Male, healthy, active. Since my freshman year of college (18 y/o) I have been getting headaches regularly. Never had them before. They are regular, daily and usually come on at the same time everyday, early evening and last 4-8 hrs, and have lasted longer. They are usually so severe that I cant open my eyes due to light sensitivity, I feel nausea, and the pain changes from sharp to dull with position changes. these headaches last for months (say 4 to 5) then disappear for a period (say 2 months) then return again. I have no activity changes to explain why this is the case. I have also experienced 2 or 3 migraines so bad that I had to go to the hospital and be treated. I hope someone, a specialist, doctor, or someone in the same situation can shed light on my symptoms and recommend a course of action. Thank you all for your time and help.
