Seperated AC jt with no initial pain

I felt pain in my neck after doing a series of forward rolls with no hands, at an adult gymnastics session. I was unable to keep directional control throughout the rolls.

I carried on after this for an hour, because the neck pain can be common (where the rods in my back attach from a scoliosis op) and always goes away after a few days.

When I got home I saw in the mirror that my clavicle bone was poking up on the left shoulder.

The next day I struggled doing heavy lifting at the greengrocers (muscles fatiguing quickly, and joint felt unstable).

It got diagnosed at A&E from an xray as a grade 2 sprain, and I have been trying to function normally since, as it did improve initially. I am a dance, rhythmic gymnastics coach though, so do not want the shoulder to get worse and feel it has done already when i rolled over it the other day.

Any ideas for exercises? I already stretch my pecs and strengthen my deltiod and trapezius. I am guessing there is no way muscle strength will ever push the bone back into normal place? I will just have to keep it as strong and stable as possible.
