--involves the lateral fermoral cutaneous nerve (which is only a sensory nerve--no motor functions) that runs along from the lower pelvis along the outside of the thigh, terminating slightly above the knee. It can become compressed anywhere along that length, although the pelvic area is the most common site for that.

If you're having groin pain, along the INNER part of the thigh, it's likely that's a distinct issue from meralgia parasthetica. It is certainly possible you have compression in the pelvic area affecting more than one nerve tract. Or, the problems could stem from higher up in the lumbar spine. It would seem an MRI of these areas might be in order.
