If you think it's sinus infection and have green 'stuff' coming out, get a Neti Pot. It sounds gross, but you basically hold your head over a sink and run warm saline solution in one nostril, through your sinuses and out the other nostril. Docs recommend it and it WILL relieve the sinus pressure and help you feel better.

If you can't get out, your wife should be able to get one at Walgreens or WallyWorld.
Hope you feel better. I used to get cluster migraines every weekend. They'd end with me bowing to the white porcelain god, puking my guts up, but the headache would go away. Made me want to banish weekends.
