Felt Something "Shift" Under The Wrap

I was hanging last night, straight out, bib starter, 7lbs, my fourth 15 minute set of the day. I heard and felt something internal move under the wrap. No pain, no discoloration, no sign of any trauma.

Prior to this, when hanging the feeling when hanging was much “tighter” on the right side. Immediately after this event, the tightness on the right side was gone.

Thoughts on what this was?

Although that scenario is not the usual way this happens, it sounds like a lig pop. Ligament pops usually occur when stretching straight down with considerable force and although quite freaky, they are completely harmless.

Thanks gprent, I had suspected as much yet wanted opinions from those more experienced than I.

Are there any new considerations I should adapt as a result of this?

I wouldn’t change anything right now, but if it continues to happen and is a little too freaky, just change the direction of weight and see if it stops.
