Do a search on Methicillin Resistant Staph Auerus. It is referred to as "mersa", MRSA. If you have a sore that won't heal or one that is draining you need to see your doctor so he/she can do a culture of the sore. That is the only way to know if it is MRSA or not. There are medications that can cure it. You may also have to do whole body scrubs with an antibacterial agent for about a week. If you think you have it, do yourself a favor and go to the doctor or clinic.
