Any, is it possible that by favoring the right shoulder you over did things with the left and its flared up? Try ointment rubs and hearing pads or ice. My bursitis trends to hit one joint and then the other, both hips and shoulders. I hope it gets better soon!
@ JT2, I'm not sure what part of the shoulder that is. My dad you're something in his and the docs did a minor surgery repair. It scared up real bad, and due to his age (84 then) and limited mobility, they ended up doing a complete shoulder replacement. If they do surgery on your year, make sure to do the therapy like they teach you, to keep your mobility.
Good luck & God bless both of you. (((Hugs))) & prayers! 🙏🌼
