revenge of the hip

I guess endorphins and ibuprofen kept it down on Saturday. Not moving on Sunday probably kept it away as well. I took two steps off the elevator at work yesterday and, with my weak muscles, extended the joint enough that the pain came back sharply. I still don't know what this is. It feels like it's really down in the joint. Who knows? I'm hoping with some rest that it will just go away. No exercise at all so far. I'm considering 30 minutes on the elliptical tomorrow. Maybe not though. No rush.
