Chapter 2: Common Causes to Consider
Warts: These may appear as firm, rough growths and can spread through direct contact or contaminated surfaces. Their texture varies, and not every raised bump is a wart.
Dyshidrotic eczema: This often causes small, fluid-filled blisters accompanied by intense itching. Episodes may recur, and triggers can include irritants, sweating, or stress in some people.
Contact dermatitis: Soaps, cleaning products, gloves, metals, and other substances can irritate the skin or trigger an allergic reaction. Redness, itching, dryness, and cracking may occur alongside bumps.
Infections and other skin conditions: Certain infections can produce blisters or clustered lesions. Because treatments differ, a clinician may need to examine the skin before recommending medication.
Avoid squeezing, cutting, or scratching the bumps. These actions can injure the skin, increase irritation, and potentially spread some conditions.
