Chapter 3: Symptoms That Deserve Attention
The symptoms accompanying the bumps can provide useful clues. Itching may occur with eczema or dermatitis, while rough, firm growths may be consistent with warts. Pain, warmth, swelling, or discharge can suggest inflammation or infection.
Arrange a medical appointment if the bumps persist, multiply, keep returning, affect the nails, or interfere with daily activities. Seek prompt medical attention if the area becomes increasingly red, hot, swollen, or painful, or if pus or fever develops.
If you have a weakened immune system or diabetes, it is sensible to seek professional advice earlier when a skin problem is unexplained or worsening.
Do not rely on a photograph or online quiz to identify the condition with certainty. A clinician may diagnose it by examination and, when necessary, recommend additional testing.
