Patient's question:
In the past 45 days, I noticed a red bump on my glans, which is slightly swollen and itchy around the area. Recently, the bump has also left some pus. I had my foreskin circumcised two years ago and haven't had any sexual activity. It's likely due to the cold weather a few days ago when I didn't take a bath or change my underwear, and sometimes didn't wash my face before urinating when I finished work.Doctor's answer:
Hello,、、、。。，，，，，，；，，，，。Translation:
Hello, balanitis is an infectious purulent disease that causes local redness, swelling, heat, and pain on the head of the penis due to bacterial penetration or hematogenous dissemination. This condition is more common in young and middle-aged adults. The main clinical manifestations include:
- Acute inflammation: Local redness, swelling, heat, pain, jumping pain, fullness pain, tenderness, with particularly severe pain at night.
- Chronic inflammation: Mild local swelling and slight tenderness, slow progression, sometimes forming hard nodules. If they rupture, it is difficult for scars to form.
