Sometimes the skin on my left testicle would itch. it mostly itches after i finish taking a shower and put on my underwear. the itch isn't persistent?

Here are some ...: Glad to know the left hemiscrotal itch just transient after shower. How long has it been? Recurring each time? You may take a look at the itching spot if there is any change in color or texture of affected skin. If yes, try gentle washing without any physical or chemical irritation to it and see it may evolve. If worsening, try topical steroid. If not helpful, seek evaluation to make sure...
