My 22 year old college daughter has C-MRSA

I am hoping one of you Infectious disease nurses can answer my questions. About 3 weeks ago my daughter called home and said it looked like she had these big spider bites on her legs and one behind her ear. She said they didn't itch as much as were really painful. This was on a Friday and by Monday she called and said some of them were about the size of a baseball and had broken open with green-thick pus. Told her to go to the doctor as it sounded like staff and she probably needed an antiobiotic. She is very allergic to many antibiotics and in fact had anaphylactic shock from Rocephin and PCN. Many others she gets hives and dependent edema. The doc gave her clindamycin po and said if not better in a couple of days to get back in. Two days later I went with her to the doc and they said she needed to get to the medical center(hospital) for IV antibiotics. They started her on IV vanc and IV clindamycin for 4 days and sent her home on po clindamycin. They were healing up nicely but they forgot to get a culture so do one on the 3rd hospital day. We went for her post-hospital visit and when they called her to go back to the exam room they were in full isolation protocal. They said the cultures came back C-MRSA. She was to continue on the oral clidamycin and see the infectious disease doctor in a week. She saw him and he said the vanc saved her life and to call if she saw they were returning. This doctor is from a large hospital 350 miles away and have a clinic twice a month at our smaller hospital. A couple of days ago she started getting new boils on her left leg. She called the doctor's office and was told to come in. They GP doctor she saw wasn't concerned at all and wanted to give her a script for Bactrim. She is very allergic to it so refused to take the script. He told her this C-MRSA is no big deal and she should quit making such a big deal about it. Today she has developed a couple more boils and is very scared. It seems like one doctor is real concerned and the next doctor not concerned at all. I can't get ahold of the infectious disease doctor and of course now it is a weekend so can't talk to the ID doctor until Monday. Am I wrong to be so concerned over this? Maybe we are over-reacting as one doctor says but I don't know that much about C-MRSA so maybe I am. Do you think she can wait for 3 days to see the ID doc? They aren't baseball size yet but about the size of an egg. Can anyone help me out with this problem and give some advice please?
