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've noticed the same condition. I typically wear mine on the looser side. One notch down would be snug and would spare me the incessant Siri interuptions but would not be uncomfortable. However, I just prefer the comfort of one notch looser. I am increasingly concerned about the long-term effect of the continuous IR light on the skin. Irritation, I can live with (for now). According to researchers, it SOUNDS like IR does not carry the same well-know risks as UV, but it's always qualified by "there's insufficient evidence to conclude..". But, a light burn seems like it should be a light burn and perhaps there's just not enough research on long-term concentrated application of IR.

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, so I immediately took off the watch and threw it across the room and went back to sleep. For about six weeks after that my wrist was very sore as if somebody had hit it with a hammer multiple times. I returned the watch, I tried to dissuade my ex-wife and my daughter from wearing their's, but they have no issues so they ignored me. I will never touch an Apple Watch ever again.

LD150, think before you speak.... i've not noticed you're quick to respond to many people without using your brain first. Clearly, it's the watch, but clearly it affects some negatively while not affecting others, but as anyone with sense would concur, the watch is the unknown variable, and in my case as well as many others evidently, this watch has a consistent adverse affect on those of us who are seemingly hypersensitive to it including the physician who commenced this thread. I didn't have these issues until I wore the watch, so you stand corrected, it's NOT me that caused this, it WAS the watch.

That pimple? The author does claim to be a medic but hasn’t noticed that if humans wear watches, rings, spectacles for a long time that the skin and fat become depressed semi permanently. I have grooves behind my ears and dents in my nose from 20 years of spectacle wearing but I don’t complain to Specsavers.

Anyone married more than a few years take a look at your ring finger.

Some people just want to join the blame Apple band wagon.

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.
