Do you slouch over a laptop a lot

left/right?

Side sleeper?

Stretches?

Interesting, but sorry to hear that. Back of shoulder, top or front of shoulder? How long have you had this issue?

PT

Go see a physical therapy person. They will give you some exercises. I get muscle pain on my left side from sleeping. I need to get after it again, did great for about 6 months, then I slacked off on the exercises.

If it is constant , you may have torn a infraspinatus/supraspinatus tendon/ligament. Which means you need to rest the shoulder/arm completely. Get an ultrasound of the area. It is important to know exactly what is going on to prevent further damage and/or trauma to the area.

Hot water bottle

Good massage, also try a THC gummie at night, I wake up and mymuscles are super relaxed

Kettlebell on chest and roll spot on top of foam roller

My experience has been that it’s caused by tight chest muscles. Rolling with a handball against a door is an almost nightly ritual for me. Do both chest and back but don’t overdo it. Just make it part of your routine.

Get a quality cupping set. Force compliance in your troubled areas.

Face pulls and dead hangs from a pull up bar helped me

Reformer pilates

Depends where it is. If it’s glenohumeral or acromioclavicular, you can do a dead hang from a pull up bar and that should “create” space to give you more rotation among the capsule. If it’s more neck related, a bit more intricate to resolve. Tough to say without seeing exactly where you...

I have something similar since 2009. Not solved yet
