Hi, I'm new here, I'll get right to the point. I'm 50, healthy as a horse.... BUT:
When I wake up in the morning (or, lay motionless for over one hour), all of my joints feel like they've been epoxied INTO PLACE! And no matter what limb I move, I feel like I'm breaking something (exKROOOOshiating pain!). After I move around for 2 minutes, everything is fine.
Here's a less dramatic example.
