Groin yeast infection: what to know

A groin yeast infection usually refers to yeast overgrowth affecting the vulva or vagina, with itching, soreness, irritation, and sometimes discharge. The outer skin may look red or swollen, and urination or sex can sting when tissue is inflamed. These symptoms overlap with other infections and skin conditions, so a familiar pattern is not always enough to choose treatment safely.

Vaginal thrush is caused by an overgrowth of Candida, a yeast that can live on the body without causing symptoms. Moisture, friction, antibiotics, hormonal changes, or a disrupted local balance may contribute. Marked itching is common, while discharge may be thick and pale but does not have to be present. Strong odour, green or grey discharge, sores, pelvic pain, or fever suggests another problem or a mixed infection and merits assessment.

Keep the area dry, wash gently with water or an unperfumed cleanser, and change out of damp clothing. Avoid douching, scented washes, deodorants, and scratching. If symptoms are new, severe, recurrent, or unlike a previous diagnosed episode, speak with a clinician before self-treating. Antifungal treatment for thrush may be topical or oral, but the right option depends on pregnancy, medicines, health conditions, and whether the diagnosis is clear.

Arrange prompt care for fever, lower abdominal pain, sores, significant swelling, bleeding unrelated to a period, or symptoms after a new sexual partner. Seek advice during pregnancy or if diabetes or immune problems may affect treatment. Get reviewed when symptoms do not improve after treatment, return repeatedly, or include unusual discharge or odour.

Does this look like thrush or another cause of vulval irritation? Do I need a swab? Which treatment is suitable with my medicines or pregnancy status? How should I prevent irritation while the skin heals?
