??????Hello, according to your description, it is recommended that you go to the hospital for a check-up to determine if you may have orchitis and epididymitis, or if you may have spermatic cord, seminal vesiculitis, etc. In daily life, pay attention to reducing the frequency of sexual activity and quitting the habit of masturbation. Avoid spicy foods in your diet and abstain from alcohol. Wear loose cotton underwear and pay attention to personal hygiene.
