I have this sinus problem since I was 25. I used to have heavy headaches whenever I drink anything cold or when I sweat. When I met a general physician they suggested me some meds which temporary fixed my headache. Nowadays quiet often I get headaches and also couldn't swallow comfortably. Feels like I have those mucus in my lungs and sometimes I couldn't breathe easy when I lie down. Is this related? Should I meet a ENT specialist or again a General Physician?
