Syphilis starts with a single, painless sore, known as a chancre.
Because it does not hurt, many people ignore it — allowing the infection to progress.
Early treatment with antibiotics is highly effective, making evaluation essential.
7. Chronic Skin Conditions (Lichen Sclerosus, Lichen Planus)
These non-infectious inflammatory conditions can cause:
- Intense itching
- Thin or fragile skin
- White patches
- Flat or discolored bumps
These require medical diagnosis and long-term management to prevent progression.
When You Should See a Doctor
Seek medical attention if the bump:
- lasts longer than two weeks
- becomes painful, grows, or changes color
- bleeds or cracks
- comes with fever or significant discomfort
- causes pain during intimacy
- appears with recurring sores or itching
Getting evaluated early provides clarity and prevents complications.
