Jock itch usually begins with a reddened area of skin that spreads out from the crease in the groin in a half-moon shape onto the upper thigh. The border of the rash may consist of a line of small, raised blisters. The rash often itches or burns, and the skin may be flaky or scaly.
When to see a doctor
See your doctor if you have a rash on your skin that doesn't improve within two weeks or if you treat it with over-the-counter medications and it returns within a few weeks. You may need prescription medication.
