Apple Watch Ultra 2 is causing wrist and arm pain with all-day wear

I purchased the Ultra 2 because of its longer battery life, so I could track my sleep etc. With my SE I normally charged the watch while I slept, so I wasn’t tracking sleep data. With the increased time per day wearing , and going from SE to ultra 2, I’m experiencing arm / nerve discomfort pain in my wrist and upper arm. If I stop wearing the watch, discomfort disappears. Bummer that I’ll have to go back to 16 hours or less per day of wearing the watch.Hopefully it isn’t creating long term nervous damage? I’m an engineer and not a hypochondriac :-)
