Hi,

Trampolining is the sport.

I have been doing strengthening exercises with tension bands for two weeks and basic movements before that.

It happened while coaching trampolining, I was catching a performer and their force was put against the arm. On previous occurrences it has happened when performing myself, on take off to a move.

I put it back in myself rolling onto my side and bringing right arm over towards left hip.

This is the third time it has happened, but was less painful (which led to thinking it was a subluxation) although it was harder to put back in than previously.

Many Thanks!
