Last night I had a sudden headache that quickly turned into the worst headache I've ever had. I began to vomit until I couldn't any more. This went on for hours with shaking and shivers. I thought I felt warm but didn't check my temperature. The pain was brought down after a long shower, to where I was able to fall asleep. I felt fine since then, but had a very messy nosebleed today. I would sneeze here and there, and for a split moment I would feel the massive pain I had the night before. In the same location which is: mostly the right side of the forehead near the top of my eye. Getting nosebleeds are extremely rare for me, especially this bad. It didn't last long though, about 10 minutes. Headaches are fairly common for me, so to say that this was the worst one is significant to me. I did not hit my head. I took 2, 200mg ibuprofen pills for that headache, and they didn't do anything for me. Just one of those pills would normally work wonders for me. Should I be concerned after this?
