<s>[INST] Hello doctor, I have a red shiny patch on penis glans. For one week I had three red, shiny spots on my penis glans. Now wrinkles were appearing. Initially, they were few spots but now one left. They are not itching or hurting. I applied the Itch Guard on it for week. I want it to be cured completely. Please kindly advise. [/INST] Hi. Looking at the spot, I can list a few possibilities like candidal balanoposthitis, herpes, or genital psoriasis. Any history of unprotected sexual intercourse? If yes, how many days back? Were there any blisters or pus-filled lesions before this spot appeared? </s>
