Skin in the groin goes through a lot — heat, sweat, friction, tight waistbands, and hair removal — so irritation there is common. One frequent cause is ingrown hairs, where a shaved or waxed hair curls under the skin and forms a red, itchy, sometimes tender bump. Warm compresses, gentle exfoliation, loose clothing, and taking a break from shaving usually help more than squeezing.
