I have a big red mark in my inner right thigh and vaginal lips. It doesn't hurt nor is it hotter than thighs should be. It seems to have bruises? I'm very confused at what it is and hoped I could have a little help from here. I put baby powder on it and have had it for maybe two to three days. It doesn't get smaller or larger with the powder on and I thought it was dry skin but that isn't it. I thought about a rash but I'm very clean(bigger person yes but very clean) I tend to have to sit on a stool a lot for a class I take and have that spot resting on the edge of the stool so maybe that could be it. I felt it and it had at the back the feeling of stretch marks. Any help?
