I Am 20years old male. In my private area between thighs and scrotum and also on the pennis shaft one pimple like swellings on each area are observed from 2 days. Also I did not masturbated from 20 days and my left testicle is little bit down sagging more than right one but I do not have any pain in scrotum. Is this due to unhygienic diet or any other reason? Is it important for immediate checkup?
