Liftsiron is correct but the % that cause intestinal strangulation is very very very low. Hernias are more a bothersome thing-- not very acute. They do not ALL bulge out either. Sometimes the tear causes the bulge to go into the scrotal area so it is not as visible. Epididymitis usually presents as a dull ache that after a while makes you want to tear someones face off. If you palpate your testicles, you will have a tender area where the infection(epididymis) is.
If it is epididymitis, the txmt is support, rest and usually antibiotics. Sometimes, it clears with just rest and support.
At this point, wear your tighty whities while training and take some Motrin. If symptoms dont resolve in 1-2 weeks or worsen seek care from a doc. Been there done all the above stuff incl hernia surgery. Fun!
