Hey Willg, thanks for the update.
I had surgery about a month before you and had the exact same problems and panic reaction.
Even though I am taking my rehab really slow I am feeling better every week. Before the surgery I couldn't even hike or bike without pain but this past weekend I went to Yosemite, biked, hiked a lot and felt great. It will probably be a while before I can play soccer but I can see a lot of progress already.
Like many others here I recommend patience after surgery.
Also this rehab exercises really helped me, though I didn't follow the timeline on ithttp://www.physioroom.com/injuries/groin_and_pelvis/sports_hernia_exer.php
I will keep posting...
Best wishes for everyone here and thanks for sharing.
