A red, scaly rash with raised edges may be jock itch, a fungal infection that thrives in warm, moist areas. Contact dermatitis can also occur after exposure to fragranced soaps, detergents, lotions, dyes, or certain fabrics.
Keeping the area clean and dry, wearing loose breathable clothing, using gentle fragrance-free products, and avoiding shaving until the skin heals may help. Do not share towels or razors, as fungi and bacteria can spread through personal items.
Seek medical advice if the rash lasts longer than two weeks, spreads quickly, repeatedly returns, or causes severe pain, swelling, pus, or fever. A healthcare professional can identify the cause and recommend the correct treatment.
