Hi John
Congratulations on your new hip.
You are early in recovery and sometimes just doing a little too much can cause pain or problems. Groin pain is a common complaint. It is often from muscle problems. I have collected a group of stories from people with groin pain. Some people had it for months to years while others only had it for awhile after surgery. Here is the page
http://www.surfacehippy.info/groinpain.phpEarly on, any time you start to hurt, you have most likely done too much. Take it easy for a day or so. My doctor always said - listen to your body.
If you get too concerned - give your doctor a call.
If you had a femur neck fracture of loose acetabular cup - it would really, really hurt. A terrible, won't go away pain. So I would not be too worried about the terrible things that are running thru your head.
It is early on - so take it easy. If it hurts - don't do it or do less.
Good Luck.
Pat
