Hi there.
Not much comfort but a little advice. As a nurse (and a fellow bandster), in my line of work, I deal with people with or have had MRSA all the time and have never had it or caught it.
Do not worry about passing it to family members or partners. As long as you carry out strict hand washing and keep the area covered at all times, they will not pick up the infection. It would be a good idea to buy some alchohol gel too, this is good for disinfecting your hands after washing.
Wounds which carry MRSA sometimes heal up alone without any intervention (usually in younger, healthier people). Creams alone do not always work sometimes they need to be given with I.V antibiotics. Here in the UK medics are loathe to give antibiotics unless the patient is really ill as the amount of antibiotics that can treat MRSA are few and far between and this infection is becoming incredibly resistant to nearly all antibiotics!!!
Please try not to worry too much. Wounds with MRSA DO heal but can just take a little bit more time.
Can I just add, as a health professional, it makes me so mad the way other health professionals stigmatise people with or have had MRSA - there is absolutely nothing to get in a state about as long as people are using precautions!!!!!
