Hi there Shell,

No doubt the boot changed your gait and affected your hip. It should have gone away now that the boot is gone.

This might be a long shot - but if you have an arthritic hip, the pain manifests as groin pain. I had this happen and it surprised me, but the ball and socket for the hip lie directly under the groin. Anyway the boot and changed gait may have inflamed the hip.

I'd get an MRI and meet with a hip surgeon. Again, a bit of a long shot but maybe worth checking out. Hopefully it is bursitis or tendonitis brought on by then change in your gait. That should resolve soon.

All the best!

Joe
