The foreskin in front is always red and itchy, what's the matter?

Patient's question:

Male 17 Don't know what disease it is, it has recurred today
Why is my foreskin always red in front? It's also itchy and keeps recurring. Who knows what's going on? It's accompanied by swollen inguinal lymph nodes. It goes away when it's better, but it comes back when it flares up. In one and a half months, it has occurred three times. What's going on? My foreskin isn't long either! There are no symptoms of a long foreskin that you mentioned! What's going on? Is it just inflammation? And after it heals, the front skin isn't smooth either, with some wrinkles? What's going on?
I haven't done anything dirty. I'm very busy with my studies. Based on your experience

Doctor's answer:

Hello, your condition may be balanoposthitis, which refers to inflammation of the inner foreskin and glans penis. Balanoposthitis will not heal on its own if left untreated. In the early stages, patients may experience local redness, a burning sensation, and itching on the glans. If not treated promptly, there may also be symptoms such as erosion or erythema on the glans. If balanoposthitis is left untreated for a long time, it may lead to other complications, such as prostatitis, orchitis, urethritis, and other reproductive system infections. First, identify the cause of your balanoposthitis—whether it is caused by bacteria, viruses, mycoplasma, or chlamydia—to find the root cause and provide targeted treatment. Under the guidance of a doctor, take medication specifically for your condition to completely cure the balanoposthitis.
