My symptoms have lasted since October..I've had inconsistent headache on the left side of my head above my eyes. Blocked nostril on my left side (occasional blood from this nostril) and constant cold with occasional dizzy spells. I've been given various antibiotics for a sinus infection which have been 5-7 days courses. These have worked until the day I stop taking them. Last two days I have had a constantly numb cheek. I had my nose broken three years ago, could a deviated septum cause all these problems?
