Every time I do an hour Zumba class, Body Combat, or a combination of YouTube videos, my wrist, and arm sweat with the cast on. I take it off for 10 minutes for it to cool down, gently wash it, and then put talc on it so that I can get the cast back on.
The part of the cast where I have my finger in to show you, rubs the still swollen top of my wrist. When it sweats it get really sore, so I only use my left arm/hand part of the workout. I can’t wait until the 20th to go back. This one will have been on 3 weeks then, and a total of 6 and a half weeks since it happened.
