 [ Symptoms ] i had a minor heart attackmyocardial infarction [ Disease ] the ent does care but mrsa assuming he has a community acquired type and not the more severe hospital type is very challenging to treat you can ask for an infectious disease consultation but your ent may be doing the best that can be done you can also ask to see another ent for a second opinion sometimes we have no idea where the infection came from but we do know it came from people some people are carriers and do not know it some kids get it in day care now i can understand your frustrations so the only thing you can do is try to get his evaluation and treatment to a higher level but getting a second opinion or adding an infectious disease specialist to the treatment team
