question: I have noticed right sided groin region pain that seemed to show mild sensitivity to my right testicle as well.  It is sore at rest.  It began this morning during a shower, however last night I was demonstrating a dead lift exercise to a client and remember feeling a mild strain sensation in my right groin.  Being a physiotherapist I am inclined to believe it is muscular but am concerned by the soreness at rest.  Is there any way to easily differentiate between an inguinal hernia and a psoas or hip flexor strain?
