What is Jock Itch?
Jock itch (tinea cruris) is a common fungal infection affecting the groin, inner thighs, and buttocks. It’s caused by the same family of fungi responsible for athlete’s foot — meaning it can spread from your feet to your groin if left untreated.
Signs to watch for: a red or brownish ring-shaped rash, persistent itching or burning, dry or flaking skin, and discomfort that worsens with sweat or physical activity.
Who’s at risk? Tight clothing, excess moisture, shared towels or gym equipment, and a weakened immune system all increase your chances.
While OTC antifungal creams can address mild cases, recurring or spreading infections often require prescription treatment. A board-certified dermatologist can also rule out conditions like psoriasis or eczema, which closely mimic jock itch. Early, accurate diagnosis means faster relief — and fewer relapses.
