Arm stretch - this is an area where I do have pain sometimes, it happens more often with my left arm (holding things) than my right arm (doing things)

His suggestion is if you do a lot of arm/hand work, this is a stretch to do several times a day. I think he mentioned 5 times a day.

I do not feel a defined stretch when I do it. But then my arm does feel better. If you type a lot, I think it is super important to check arm and hand positioning. Like height of chair. Being able to rest your forearms on something. Etc.
