It’s not just me! I got my watch 9 days ago for Christmas from my husband and I started having the pain almost immediately. It does not appear to be dermatological. The pain feels neuropathic (numbness, tingling, electrical) with the two main focal points for me being the wrist and elbow. The pain persists regardless of how the watch is worn and resolves when the watch is removed for several hours to a day.
Objectively, I do not know how the watch is causing this reaction but for me the location and temporal nature of the pain in association with use of the watch and resolution when the watch is removed, along with the fact that I have no previous history of arm pain (neuropathic or otherwise) and no other concomitant disease states that would likely cause neuropathic pain, leads me to be fairly confident in my conclusion that the watch is causing the pain.
As tempted as I am to try to stick it out, the pain is only getting worse and nerve pain can always be an indication of nerve damage. I’m so disappointed but my next step will be to look into how to return the watch. I do not suggest anyone ignore or try to preserve through this pain. Pain is your body’s way of telling you something is wrong.
