Hello,
I have been to a skating rink (not on ice) and I borrowed some roller skates. I got a blister that is now scared over (like a crust) which means that it bled at some point I guess. The skates were not mine and were borrowed from the venue and the blister occurred where my foot rubbed against the shoe (no socks on). Is that somehow a problem, considering there is friction, a wound and direct exposure to whatever is left on the roller skates from the person before.
thank you.
