bacterial infection
"I have had a sinus infection for 3 years now, plus Upper respiratory infection and ear infections during the really bad times. I was cultured with Staph A. and Pseudomonas that was resistant to a lot of the antibotics except doxycycline and Augmentin but I'm allergic to penicillin so doxycycline it is. 100mg 2xday and the first few days it is hard because everything is dying and my sinuses are draining like crazy but its the only things that's working. Don't lay down for an hr after taking the pill, it did burn my throat horribly but I have not had any other side effects from it except the sun sensitivity. I think this is a small price to pay to feel better and get my life back especially since the chronic fatigue from the constant infection is severe."
