I have sores on my thighs and groin area from them rubbing together and sweating, what can I do to take away the swelling and pain?

Intertrigo. Intertrigo (intertriginous dermatitis) is an inflammatory condition of skin folds, induced or aggravated by heat, moisture, maceration, friction, and lack of air circulation. Intertrigo frequently is worsened or colonized by infection, which most commonly is candidal but also may be bacterial, fungal, or viral. Treatment is with a mild cortisone cream plus an antifungal cream. I prescribe vytone.
