Apple Watch Ultra 2 causing arm pain, pins and needles.

A couple of days ago, my Apple Watch stopped recording vital signs. Since then, I’ve been experiencing excruciating pain in my arm, along with pins and needles and a “dead arm” sensation. I contacted Apple Support, and after running diagnostics, they identified two hardware issues that appear to be preventing the watch from tracking vitals properly.

I’ve been using an Apple Watch since the Series 1 and have never had anything like this happen before. I’m curious—has anyone else experienced this issue? Could a hardware malfunction be interfering with signals in my arm and causing the pain?

Since I stopped wearing the watch, the pain has subsided while I wait for it to be repaired. Any insights would be appreciated!
