My husband developed aerosinusitis (sinus barotrauma ) on descent of an airplane, and has had a sharp, severe headache localized in the brow region over his right eye, sometimes shooting through the eye as well, for over 48h. He has now had some clotted blood come out of his nostrils as well. How can he treat himself at home before he is able to see a doctor, and he is in a country without a family physician, so where should he go/who should he ask for help?
