My testicles started twitching one day after I ejaculated. It has been going on for about a week now and it doesn't hurt but feels uncomfortable and annoying. The twitching goes on for a good while then stops but comes back. I am wondering if I should get this checked and if it's anything I should worry about. I also noticed a dent on top between of my left testicle and scrotum (dent is not on testicle) but that occurred a couple days after.
