@mawr yeah, been having steadily increasing pain, weakness and stiffness in it for the last 6 months.
Thankfully the orthopedic specialist was confident that combination of PT, icing, ergo (desk, sleeping) changes and some short term meds would sort it out.. and the stuff I was really afraid of (like the bicep anchor wearing out frequently happens after 15-20 years and would need surgery to fix) but the imaging shows it is still good!
@mawr though because of the stiffness and pain, they are doing an anti-inflamatory injection guided by ultra-sound next week.. which should get the inflammation down enough I can do the PT. He was happy to hear I'd been icing it and I should keep doing it.. couple of times every day and then told me to definitely stop using a sling, even if it hurts.. the sling is much more likely to cause problems (frozen shoulder).
@mawr also gave me a medical authorization for ergonomic workstation evaluation and some other stuff.. though I don't need to worry about that too much.. current employer gives me 400/yr for stuff like that and 2k as new employee, so I'm looking at powered sit-stand desks this weekend, our HR rep sent me the form right before the end of the day with as long as it's from any major vendor won't be a problem.
@mawr I have that same keyboard!
Work also gave me the non-rgb one when I started.. really like it.. very happy with the mx browns and how it feels/is not super loud!
Got a solid chair.. though after we move I may trade up at some point, steelcase leap v2. which is nice except it is like "sit like this" super adjustable.. I keep eyeing the gesture because I like to shift around a lot and the leap doesn't do that well! Hopefully desk height adjustment and being able swap sit/stand will help
@wobblewuffess I fell in love with my kneeling chairs because they force me to build core strength and helped me fix my posture at the same time 
@mawr Makes sense.. I really want to do the sitting/standing powered desk thing.. because while I don't want to stand all the time.. just being able to swap it up regularly over the course of the day would be really nice and probably a lot better for my back and joints!
@wobblewuffess I hope it helps you out friend!
I had to ergo my everything a while ago and gosh I'm so thankful just for the range of options a sit/stand desk provides.
Kinesis makes mechanical keyboards now! They have an RGB one under a new gaming brand, which is my current one :3
