What disease is it when there are red blood vessels and small yellow dots on the scrotum?

Patient's question:

Gender: Male
Age: 22
No sexual experience
Many red blood vessels and small yellow spots can be seen on the scrotum. Is this a disease?
I previously had a urinary tract infection, which was suspected to be chlamydia infection. After taking medication and intravenous drip treatment, the check-up results were negative. I also had pruritus, and the doctor prescribed medication and powder. After using them for a while, it improved significantly, but in summer or in hot and humid conditions, the scrotum remains moist and itchy. Drinking alcohol and hand scratching also cause itching. Can pruritus be cured?

Doctor's answer:

Hello: Based on your condition, it may be considered as eczema-like dermatitis. From your current symptoms, you can take Longdan Xiaogang Pill to regulate the damp-heat in your feet! I believe everyone knows that orchitis can cause significant harm to patients, so it's important to seek treatment as soon as possible. In daily life, pay attention to dietary issues, and maintain a light diet, avoiding foods. Additionally, regular follow-up visits can be scheduled if necessary.
