###Human: Does excess body heat cause swelling in the groin area? ###Assistant: Hello. Do you have itching and a similar skin lesion on another side of the thigh? Is this the first time you are having this problem? In the picture (attachment removed to protect patient identity), it looks like tinea cruris which is a fungal infection of the groin. The picture is not very clear. I do not see any fluid-filled blisters. Is there oozing of fluid from the bumps?
