Saturday me and a friend biked all over north Dallas/addison for about 25 miles during 10:30 - 11:30 and 1:00 - 3:30. I put sunblock on (this was a clear day/not a cloud) and I saw that right when I got home, I had sunburn along my arms pretty bad, heh except for the areas where I rolled the sunblock stick on me - it looks funny. Well neways, today 2nd period I went up stairs and had a pounding headrush, which was horrible. Then I felt better. By 9th period about half my right side of my right eye's vision was grainy and flashy as if a light was shining everywhere I saw in that qt. vision. By 10th I was feverish, had chills, fatigue, dizziness, borderling vomiting, and couldn't even hold my head up long. So I left sick. Now after some research I displayed symptoms of sun poisioning (don't know the medical term) but the symptoms I read about occured from right after sun exposure to about 12 hours later. Not 48 hours later. Yikes. I wonder what caused it. This occur to any of yall before?
