Appple watch pain

Okay....I have had my Apple Watch for nearly a year and I love it. The last couple of weeks, though, my left hand, lower arm, and upper arm. It feels like an arthritis pain--a dull pain deep in my muscles or bones. There is no reason for it, but I Googled Apple Watch and pain and I see I am not alone. I took it off today and two hours later the pain is gone. Obviously I am going to try the other wrist next to see if it happens again. It did take a year for the pain to start, so it may take awhile. I am worried damage is being done even if pain isn't occurring.

Has anyone else experienced this?
