Hi, my name is Teresa and I am 39 years old. I have had frequent headaches. Most prevantly they start at the base of my head. Some can affect my eyes with sensitivity to light. Last night I had one and I got really nauseas and felt like I was going to pass out. Most of what I have read about Tension and Migraines do not define this type of headache. I took Over the counter tylenol and 2 ibuprofens last night and though the pain diminished the nausea and that passing out sort of feeling was still there. I finally took 1/2 clonzepam and it seemed to get better. What kind of headache is this?
