Hey, I feel you, it's really annoying. These shoulder dislocations also always hurt me, and getting it to go back into the socket always scares me. What I do during flares is first  being aware of my movements, not to make sharp or excessive movements. Secondly, I have a certain hand where the shoulder usually dislocates, and there I walk around with a sling to remind myself that this hand is problematic. hope it helps.

Kinesiology tape!!

I bought a brace online I looked up shoulder braces it helps its hard for me to get it to feel comfortable I'm kinda small I hope that helps

You described my shoulder completely I'm at the point I'm looking into see if something surgically can be done
