What Causes A Bruise On The Inner Thigh?

I don t really know how to form this into a question, but I wore a girdle (oh boy I know). Which isn t an unusual phenomenon in my life, but this time it was a bit tight around my pelvic/groin (?) area. Which was about a month or so ago, and since then ive had welts down at the very top of my inner thighs, and they re welting to the point they re making my skin wrinkled? I ve never had a well before so I m not sure if that s normal. There was some skin peeling in the beginning, and now there isn t. But the skin is still very irritated, and such. It s also discolored, and by that I mean. I m a very pale individual, and the color is like a reddish-brown, with a tint of purple. So basically a big bruise, so should I get this checked out. Or should I be applying some type of cream to the area?
