Tips on dealing with carpal tunnel?

Worked in F&B for about 10 yrs, been a barista for almost 3 yrs. It's been far and few between since I switched to a coffee shop that uses an automatic tamp, but recently its been acting up to where I have bad discomfort especially after longer shifts. For example, this past week I went to the gym after work but could barely grasp any of the equipment it was so bad, much less lift much weight . That's probably the worst pain from carpal tunnel I've had and scared me enough to want to do something about it. I've saw that certain wrist braces and stretches help, but wanted to see if any of y'all had specific things that have helped in your experience. Typing out this post evens hurts. Thanks in advance!
