i checked myself for an inguinal hernia and i don't feel one (i can do that as i am a healthcare provider in internal medicine). that said, i have had this nagging left groin pain for awhile.

my thinking is that i have switched to taking a lot more protein (and i have been constipated) or i am simply just over-training at 6 days/week. i usually do the eliptical for cardio.

has anyone here ever experienced nagging groin pain from lifting/doing cardio too much?

...yes, i should know to take better care of myself as a healthcare provider but it seems we tend to take better care of our patients than we do ourselves!!! i tend to push myself to the extreme because that is just my personality.
