I have never had the staph infections nor am I on as much medication as you, but both of my sons had a bad bout of recurrent staph a few years back. It colonized in my younger son's skin and kept recurring--- the vicious cycle of sores, antibiotics, remission, and return had him miss 45 days of school in one year. After so many rounds of Bactrim, then trying to up his Vitamins, treating the whole family, washing daily in bleach, etc, we finally saw an infectious disease specialist who put him on a combo or rifampin and doxycycline, as well as mega doses of Vitamin C and a multi-vitamin. He was on this for a month, and then the sores were finally conquered. We still follow the protocol of not reusing towels or re-wearing clothes, not overusing antibiotic ointments or soap, always washing clothes in hot water and bleach or borax. We watch cuts closely and keep very clean. MRSA is very scary. Ask your doctor to look into the combo treatment of the antibiotics. If you even google these antibiotics with staph infections, you should get a lot of hits. I wish you the best of luck!
