Patient's question:

All symptoms: Red bumps on the glans penis
Onset time and cause: In the past two days
Treatment status: No
Help needed: What should I do

Doctor's answer:

Hello! Based on your description, it is likely that you may have balanitis, which is often caused by poor personal hygiene or excessive foreskin. The inner foreskin secretions are not cleared promptly, allowing pathogens to grow and multiply, leading to local inflammation.
Advice: For your condition, you can use potassium permanganate solution for rinsing. Pay attention to personal hygiene, change your underwear and pants frequently, and avoid spicy and irritating foods. If the recurrent episodes are caused by excessive foreskin, it is best to undergo circumcision. This will prevent the occurrence of balanitis. Maintain a light diet, avoid spicy and irritating foods, get adequate rest, and avoid overexertion. Refrain from masturbation and unprotected sex. Lead a clean and healthy lifestyle.
