I'm sorry to hear about the discomfort you're experiencing with papules in your private area. Since your syphilis (likely the "sit ulcer") test came back negative, it suggests that the papules are not related to that infection.

Papules in the genital area can have various causes, including benign conditions like pearly penile papules, Fordyce spots, or other non-infectious skin changes. Sometimes, they may be due to infections such as genital warts or molluscum contagiosum, but these usually require specific diagnosis.

Here are some general steps you can consider:

• Avoid self-treatment: Do not try to remove or treat the papules on your own with over-the-counter creams or home remedies without a clear diagnosis.
• Maintain hygiene: Keep the area clean and dry, using mild, fragrance-free soap.
• Avoid irritants: Avoid tight clothing, harsh soaps, or any products that may irritate the skin.
• Consult a dermatologist or a sexual health specialist: They can examine the papules closely, possibly perform additional tests, and provide a precise diagnosis and treatment plan if needed.

Supplements and supportive care: While no specific supplements remove papules, maintaining a balanced diet rich in vitamins (like vitamin C and zinc) can support skin health.

If you notice any changes such as pain, itching, spreading, or new symptoms, seek medical advice promptly.
