MRSA is becoming more prevalent--especially in public areas. I work in a hospital and see it all the time. Ranges from adults to babies. It is very contagious so be diligent in washing your hands and linens and making sure people around you also are dilligent in washing hands and not sharing towels etc with you.
It also is very important that you get help quickly once you take care of this episode because it has been shown to come back and the quicker that you get treatment, the quicker it gets better. Sometimes it looks like an ingrown hair, or pimple or spider bite. If you wait too long, sometimes they have to scrape the area to take the infected tissue out and then pack it until it seals back up. (since you were going to the doc on the 20th they might have done that)
Don't be afraid to seek treatment. Depending on the severity of the infection, we treat patients with IV antibiotics and they seem to work very quickly in getting the infection to quit spreading. you just have to come in frequently until progress is being made (I forgot how many hours per infusion) but usually for outpt treatments it's like 3-4 times. Also once it gets under control, you can take antibiotics orally.
definately take probiotics.
