Just very basically... have you been taking 600-800mg of ibuprofen to reduce the swelling? & Taking pseudoephedrineHCl (the original sudafed, now behind the counter but no Rx, just ID to buy) to drain away the congestion?
Also... high fat diet for your immune system (antibodies are almost 100% pure fat, with a little protein thrown in for structure), NO calcium during your antibiotics (calcium bonds to most antibiotics rendering them inert), and a lot of active culture yogurt (I know, calcium, but you're off the antibiotics for now) to reestablish the beneficial bacteria in your gut?
And... here's the "worst" of them all... have you been sleeping/ not exercising? ((exercising -and other forms of stress- stimulates adrenaline, which shuts off our immune systems))
