About 2 months ago, I felt a tingling sensation in my testicles, only for a moment, then 2 days later it came back, 4 days later it became constant. Nothing hurt, just small tingling. I usually didn't feel it except when I would lay down to sleep and be calm. About a week later it grew and at week 2 it stopped. I had no swelling, no lumps anywhere, no redness, nothing. Then about 4-5 days after it stopped, it started up again.
