I am 19, and have had an ICD since I was 15. I haven't had many episodes since. Recently I've gotten another MRSA boil on my breast right above my pacemaker. My immune system isn't at its best and this will be not the first time I've had MRSA. Is the location of this boil to be worried about? I am not sure what to think and do not want to worry myself. I am trying to get an appointment with my primary but they have yet to get back to me.
