I've had a headache for nearly a month. I went to the doc's last week and he gave me some antibiotics as he thought I had a sinus infection. The headache seemed to improve a little but when I came off them was still there. And recently it's come back again worse. Now it's horrible, i have pain on one side of my head and my snot is bloody. But I quite often have bloody snot so i'm confused help. Sorry about the weird details :P
