Is good you got through that. Would have been terrible. Re the treatment now, am totally serious about the tiny, very sharp scissors to cut the blisters to their very edge then put iodine on every tiny spot of liquid. I remember just now dad saying back then, the lotions moisten which is not good. The iodine drys. The infection is in the liquid in the blisters. So IF you EVER know of, or hear of someone with blisters there - or maybe in other places too (not the penis, i wouldn't go that far) cut the damn things to the very edge and iodine it all. Every his of moisture. You can see the moisture. iodine it, to dry it out. Forget all the other chemist lotion treatments. i think anyway, do the iodine bit first, at least.
It was Plato who said, “He, O men, is the wisest, who like Socrates, knows that his wisdom is in truth worth nothing”
