Cherry Angiomas
Small, bright-red bumps that resemble tiny drops of blood may be cherry angiomas. These harmless growths are made up of clusters of blood vessels and become more common with age.
They usually appear on the chest, back, arms, or shoulders and generally do not require treatment unless they bleed frequently or become cosmetically bothersome.
Heat Rash
Heat rash develops when sweat becomes trapped beneath the skin. It often appears during hot weather or after intense physical activity.
The rash typically consists of tiny red bumps that may itch or cause a prickling sensation. It is especially common in areas where clothing causes friction, such as the neck, chest, and underarms.
Keeping the skin cool and dry often helps the rash resolve on its own.
Eczema
Eczema, also known as atopic dermatitis, is a chronic skin condition that can cause red, itchy patches and small bumps.
Flare-ups may be triggered by stress, weather changes, allergens, or harsh skincare products. Although eczema is not contagious, it can significantly affect quality of life if symptoms become severe.
Regular moisturizing and proper skincare are important parts of managing the condition.
Folliculitis
Hair follicles can sometimes become inflamed due to bacteria, fungi, friction, or ingrown hairs. This condition, known as folliculitis, often causes small red bumps that resemble acne.
The bumps may be tender or itchy and frequently appear on areas where shaving occurs or where clothing rubs against the skin.
