There : There are five reasons for a painful testicular mass that are very concerning: - testicular torsion: when the testicle twists on itself and cuts off its blood supply, - testicular cancer - epidiymitis: inflammation of the epididymus often caused by infection - strangulated inguinal hernia - acute orchitis: infection of the testes other less concerning reasons for a testicular mass include hydrocele, varicocele, and spermatocele, but these tend to not be painful. Bottom line: you should call your doctor and be seen as soon as possible. If you are having severe pain, fever, and/or vomiting, you should go to the emergency room.

Possible hernia: Among others. Would recommend having it checked. While the scenario you present suggests a hernia, other diagnoses cannot be ruled out. See your doc at earliest convenience to have your symptoms addressed. The sooner, the better as symptoms are expected to worsen if not addressed promptly. If not established with a doc, urgent Care would be advisable.
