I'm having a swelling around my left testicle. It remains swelled up all the time. Only when I lie down on a bed or flat surface with my stomach upwards, then the swell decreases. It does no pain generally, but looks odd, looks like left testicle has grown bigger. But I noticed that both testicles are same in size. I want to know about what this condition and will it what is the remedy to decrease the swell? Does it come because of frequent masturbation? Will it be a serious problem if not treated?
