My right shoulder is making an uncomfortable snapping/grinding sound when I lift it. No pain, just gross discomfort. Additionally, my left shoulder has significantly more muscle definition/mass when I flex versus the right. Most of my joints pop/snap a lot due to being hypermobile, but my shoulder is so much worse than the others. When I lift my arms, my right collarbone protrudes and 'snaps' back into place when I lower them again.
