The Dr. from the CF clinic called today to tell me that my son's sputum "grew a bug" and he needed to be treated with antibiotics. She said the bug was MRSA. He has not yet been diagnosed with CF. Could this be another symptom that he has CF or does everyone (non CF)culture MRSA in their sputum and it doesn't mean anything? He also had a chest x-ray, but she didn't say anything about the results of that. He really doesn't have any signs of an all out infection, no fever, he just has had a wet cough for a while. Seriously, is it common for everyone to culture MRSA?-it just seems like that is the reaction-"everyone has MRSA, it's everywhere!" Does this mean that he has a higher chance of getting a CF diagnosis and should I be worried that the Dr. personally called me to tell me about the MRSA and that she wants to treat it with antibiotics? I am just so confused and worried and of course you don't think to ask these questions while the Dr. is on the phone!
