I didn’t experience the same pain that you are, but from what I’ve read, that seems possible. During post-op recovery, I did have dull pain in groin and testicles as expected, but not pre-op. I believe the nerves are connected down there which is why you may experience pain spread out to other areas, but I’m not a doctor so maybe someone else can offer factual statements.

My inguinal hernia pain was only at the hernia site, and was a very sensitive, sharp pain. Due to its location, it would affect everything I did from walking, standing, showering, coughing, laughing, wearing pants (or being naked for that matter), sitting, laying down; I couldn’t catch a break, but the pain was always only on the direct site of hernia. Walking did seem to aggravate it, though just about any movement or pressure would. Just my experience. Hopefully someone can help you.
