4. Heat Rash
In hot or humid conditions, sweat can become trapped under the skin, leading to tiny itchy bumps. Heat rash is common on the legs, especially behind the knees or on the thighs.
5. Folliculitis
When hair follicles become inflamed—often due to shaving, sweating, or tight clothing—small red bumps can form. These may itch, feel tender, or develop a small white center.
