It all started 10 weeks ago. I had a cold fever after a week sinus pain began upon the left eye. It keeps going for a month. Finally the pain started to go but now for the last 5 weeks I started to have dizziness everyday sometimes it makes me feel like i'm having a stroke. I had my blood test and every thing looks fine and next week i am going to make ct scan as well. Could this be sinus symthom ? Is it very danger ?
