Shoulder articulations that cause pain:
Flexion, adduction, abduction, transverse flexion, and transverse extension.
Should I go see the doc
Is that all? If you can still move your shoulder in a couple directions, you're not CFing properly. Excruciating joint pain and dysfunction is indicative that you're on the right path. Follow Couch's STFU therapy and you'll be fine.
Any idiot who does a 100 burpee challenge deserves to lose function in all bodyparts and be banished to Tartarus.
