What is jock itch?
Jock itch (tinea cruris) is a fungal infection in the groin area, common in men but can affect anyone. Same dermatophyte fungi as athlete's foot and ringworm.
Easily treated with topical antifungals. Prevention is about keeping the area dry and avoiding shared damp items.
Do I have jock itch? Common signs
If most of these describe what you're experiencing, telehealth may be a good next step:
What causes it
Dermatophyte fungi thriving in warm, moist groin folds. Often self-spread from athlete's foot. Sharing towels, sweaty workout clothes, public showers increase risk.
Is it contagious?
Yes, through close contact or shared items.
If you have athlete's foot too, treat both at the same time — otherwise jock itch keeps coming back from your feet.
Can it be treated online?
Easy to diagnose by photo and history. Severe infection, secondary bacterial infection, or treatment-resistant cases need in-person care.
How jock itch is treated
Topical antifungals 2x daily for 2–4 weeks: terbinafine cream works fastest. Clotrimazole, miconazole alternatives. Continue 1 week after symptoms clear. Treat any concurrent athlete's foot.
Self-care while you wait
- Dry groin thoroughly after showering
- Loose-fitting cotton underwear
- Change underwear daily, more if sweating
- Don't share towels
- Wash workout clothes after each use
- Antifungal powder during the day
- Treat athlete's foot if present
How long does it last?
Usually clears in 2–4 weeks with treatment.
