Don't tell me you buy his/hers explanation. That's very unlikely to have happened. You probably ate something infected or whatever and it so happened that that location got infected. Otherwise, maybe you got a lot of infected sweat that was pressed back into the skin from all the dunks/movements or something.
Whatever. Good you're better.
Not to intrude, because your doctor impersonating analysis is quite entertaining but for you to step in after he has been diagnosed, assume the position of the diagnosis while at the same time discredit it is fairly mind numbing on so many different levels.
ie.
Person gets sick, doesnt know whats wrong. At this time you offer no insight and no diagnoses except for a passive aggressive put down.
Person gets diagnosed and treated. You = LOL yea even though I had no idea what it was or what to do, now I see what they did/the advice they gave is completely wrong and useless. Glad you have somehow made a miraculous discovery. I will continue to have a superior attitude towards those who have much higher knowledge in this field by giving after the fact advice on the intarnetz.
While I understand the medical community may not be as advanced in Romania thus making you more hesitant, I would seriously stop, its becoming laughable.
