Adverse effects of Apple Watch Ultra

I am a physician Board Certified in Internal Medicine. In October 2022, I purchased an Apple Watch Ultra and began wearing it nearly 24 hours per day taking time off to recharge it every 2-3 days when the battery level reached levels below 20%. Starting April or May 2023, I began to notice a "burning" sensation directly under the watch itself. This sensation felt very much like a mild sunburn localized to that square inch of skin underneath the blood oxygen and heart rate sensors but did not show any discoloration. It was never what I would describe as "painful" but was uncomfortable enough that I was constantly aware of it. I tried loosening the band and taking the watch off entirely for hours at a time without improvement. Beginning about a week ago, I noticed that the skin and/or extensor muscles directly beneath the watch were becoming slightly atrophic (wasting) so I removed the watch completely and have not used it since that time. After 5-6 days not wearing the watch, my skin is not quite as sensitive and the apparent atrophy may be resolving.


My watch has all of the features available including the Titanium case, cellular features, and Apple Pay authorization.


A photo of my wrist is included. Unfortunately, I did not take the photo until I had stopped wearing the watch for about five days at which point the atrophy seemed to be resolving. I should note that I wore a Fitbit for several years prior to the Apple Watch and had to discontinue after developing pain in the wrist and hypertrophy (enlargement) of the distal ulnar head which persists to this day. The pain stopped within days but the hypertrophy has not diminished. I realize that my body may be abnormally sensitive to these things and these conditions may be rare but, in my case, I seem to have clear, objective, changes.


My reason for this post is to see if this condition is very common and whether others have experienced similar issues. Does Apple offer some kind of "fix" for this?


I appreciate any input and consideration!

All of the photos of these so called burns, from the pictures alone, I have one question,

WHY ARE YOU WEARING YOUR WATCH SO TIGHT!?

All technology no matter the size needs to breathe. All of the watches sensors work without you trying to cut off the circulation to your hand. You should be able to put at least one finger, without force, between your band and arm.

I started wearing the ultra 2 about a week ago. I notice atrophy where the watch sits atop my wrist. I’m going back to my mechanical watch.

thus, plus the spectre of radio waves on my person tells me to do it the old fashioned way.

I imagined it might be ok since so many health care workers wear Apple Watches. I don’t think they are wise.

I had the same problem but even at a worst degree. Only after one night of wearing my brand new watch, I woke up with a severe discomfort on the skin and muscle beneath the watch, as soon as I woke up it felt like somebody had been hitting my wrist with a hammer all night,

Some people have an unusual nerve placement in their wrists. If the watch is too tight and/or if you sleep on top of your wrist, the watch can press uncomfortably and cause pain. This would be the case with any large watch. Wearing a watch, any watch, at night may not be a good option for you. People who have this problem can sometimes resolve it by loosening the watch band, moving it higher or lower on their wrist, switching wrists or just not wearing it at night.


I can't say I understand why you would try to dissuade someone who doesn't have this problem from wearing the watch.

The watch is the variable. However, I find it very amusing that people immediately jump to the notion that it's the sensors. In fact, any watch can cause a "dent" in your wrist if you wear it all the time. People who wear rings all the time also experience this same thing. And lots of people are allergic to nickel. That can result in a blistering rash.
