Patient's question:

The penis has grown something similar to a carbuncle, which is quite painful. But it will disappear in a few days. What disease is this?

Doctor's answer:

According to the situation you described, it is suggested that you may have folliculitis. It is advisable to avoid various external stimuli, such as hot water washing and violent scratching. Clothing should be soft, and diet should be light. Underwear should not be made of non-absorbent, non-breathable nylon products. It is recommended to go to the hospital for examination and confirmation, and targeted treatment should be administered after a clear diagnosis.
