The twingling sensation in your testicles may not be due to epididymitis. Most men who have experienced testicular pain will tend to be more aware of their organs and may be more sensitive to any new sensations that are bothersome. Discomfort in the testicles can also be due to varicoceles and in my experience, some of these men who have been treated for epididymitis can also develop chronic prostatitis and have discomfort in the genitalia.
If you are concerned about the disturbing testicular sensation, you should have it looked at (no pun intended).
