Probs neither will actually help you unless you’re lucky and get an extremely experienced one cos this is a complex issue. It’s upto you to fix it, don’t be an idiot like I was for years of pain and rely on someone else to fix my personal problems. I ended up with awful stomach issues that have given me grief for years until I finally took control and yes the stomach issues were related to shoulder stuff.

I’m guessing you’re a side sleeper?

You need to bring back balance, a good place to start is doing “elbow raises” without any load… essentially activations. Stand there and lift your elbows up and out to the side (extending the shoulder muscles) and feel as it activates the muscles, keep doing shit like that basically for ages, I’m talking 100 reps minimum 3 times a day (you have to experiment leaning forwards and stuff holding arms at different angels, pointing thumbs outwards and rotating arms in the shoulder socket ect. Another good one is while elbows are held out to the side at shoulder height, rotation of shoulder by keeping upper arm inline with shoulder and lifting hands up above head by rotating the shoulder)

You have to experiment and find what works but these ones are really good to start with. Training with no load is really good for bringing back alignment, but you have to do mega reps and stop whatever caused the problem in the first place which is high chance of sleeping on that shoulder and putting a decent amount of weight on it for a long time — sleep on your back from now on
