Wow, the end here was a bit harsh.
But hun, I have no idea what you would do, just don't go swimming I would guess.
Personally all my scars are on my arms, and I don't SI like I used to so they look pretty clean, and if anyone asks about them, I tell them that I got attacked by a porcupine. They don't believe it and they look at me funny, but they don't try to push for more information.
So, I'm sorry I can't really help.
