What is the problem if there are bumps and ulcers on the penis? Thank you, doctor

Patient's question:

38-year-old recurrent illness

Doctor's answer:

It is estimated to be balanoposthitis, caused by general irritation and infection. Your condition may be related to excessive foreskin. You can clean the glans and foreskin with physiological saline. Persist in treatment for more than 1 week after the general symptoms disappear. If it recurs frequently, surgical treatment to remove the excessive foreskin can be considered.
