Hello,
Scrotal swelling can be due to infections like epididymitis or orchitis, hydrocele,
hernia, testicular torsion, varicocele or
surgery in the genital area. You can provide support to the scrotum by wearing an athletic supporter, apply ice to the scrotum, take warm baths if there are signs of inflammation, while lying down, place a rolled towel under your scrotum or try over-the-counter pain relievers, like acetaminophen or ibuprofen.
