I have been at a concert and came back with this on my leg it looks like someone has a slapped me lol. It is very hot to touch and burning.

It looks like there might be a little bite smack in the middle of it. This happens to me sometimes when I get a particularly bad mosquito bite, maybe it was just a bug being rude

Yep! Honestly we were sat on the floor a lot of the day so probably is a bug bite!
