| Alternative Names:
|
| Fungal infection - groin; Infection - fungal - groin; Itching in the groin; Ringworm - groin; Tinea cruris; Tinea of the groin
|
| Symptoms:
|
- Itching in groin, thigh skin folds, or anus.
- Red, raised, scaly patches that may blister and ooze. The patches often have sharply-defined edges. They are often redder around the outside with normal skin tone in the center. This may create the appearance of a ring.
- Abnormally dark or light skin.
|
| Signs and tests:
|
| Your doctor will usually diagnose jock itch based on the appearance of the skin. Tests are usually not necessary. If tests are needed to confirm the diagnosis, either a culture or a skin lesion biopsy (for example, a scraping of the skin) may show the fungus that causes jock itch.
