I got a doc who specializes in ortho and sports injuries.
If this thing doesn’t subside in a week or so I’ll be in his office.
Mine started with twinges. Then laying down on my side I would get a throbbing pain. Could still exercise at that point.
Finally went to the doc. XRay said I needed a new hip. I was in the best shape of my life at that point. Never had any issues with that hip before.
I was 46.
