home treatment for aerosinusitis? got off plane in Philadelphia from New Orleans 3 days ago. went to a dentist, had an xray at the dentist, there is no abcess, was prescribed 2 antibiotics anyway and was told my maxillary sinus cavity may be inflamed and a root canal I had years ago was very close to it and the pressure from the plane may be causing this. Help, it's still swollen, painful (to the point of crying) and advil isn't even helping and it's my face. Any suggestions? I have to go to my PCP which entails driving 45 minutes toward center city and get a referral for an ENT due to my weird insurance. I don't think I can make it that long driving in a car.
