I had a sinus infection for about three weeks.I was finally feeling better last week.Then I woke up with a migrane two days in a row.The last two days, I have been having a lot of sharp pains all over my head.At the same time, i feel alot of pressure all over as well.I feel like my head is going to explode.It lasts a long time.I feel like I am drunk,I get dizzy.I didn't have the pressure and sharp pains this bad, while i had my sinus infection. I don't know if I am getting a sinus infection again or if it is something worse.I don't have a doctor appointment for another week-will i be okay until then?
