Jock itch (tinea cruris) is a fungal infection that causes a red and itchy rash in warm and moist areas of the body. The rash often affects the groin and inner thighs and may be shaped like a ring. Jock itch gets its name because it's common in athletes. It's also common in people who sweat a lot or who are overweight.

Hello, Skyla -

Your rash needs to be looked at by a medical doctor, either a general practitioner or a dermatologist. Your healthcare insurance may provide for a visit to an urgent care clinic.

Without looking at the rash and questioning where you have been prior to the outbreak, no one can know what is causing the rash.

It could be a case of poison ivy, poison oak, or some other plant irritant. It could be a case of shingles. Who knows?

Go to a doctor.

Best wishes.

I hope this can help https://www.healthline.com/health/rashes
but it is better to consult the doctor.

Try aloe vera gel.
