Yikes! that's pretty bad.I tried to read through quite a bit of responses on here and only those that have explained the “burn” feeling such as myself, aren’t kidding.
As a random bit of scientific, “process of elimination”… those that have had the feeling of some sort of burn, what color is your hair and how fair complected are you?
I have worn an Apple Watch since the Series 2 (every series owned has been aluminum) and have never experienced this feeling beneath the wrist. Now, before someone says, “Maybe you’re allergic to titanium!?” The answer is no. I have zero allergies to most known elements (except maybe plutonium :insert nerdy radioactive joke here
I personally feel as though this is a “flash burn” (a burn caused by intense light) or basically a concentrated sunburn by the beams that monitor your BP, Heart rate, etc.
Not sure about the frequency and strength of pulses in the pervious series in comparison to the much newer models with updated firmwares and possibly stronger lights, but this is what my wrist looks like currently. Please keep in mind, I CONSTANTLY wear my Apple Watch Ultra (Ultra Orange Alpine Band) since purchased, only take it off to top off the charge and to charge it while I shower (this negates the possibility of irritants between the skin and the ceramic and sapphire crystal back) I also make sure that my wrist is completely dry before putting the Watch back on.
Additionally, I know many have mentioned hand wash being the culprit and I can also remove this from the possible causes as I never get the watch wet when washing my hands (When I wash my hands, I don’t make it a habit of washing my wrists also; I’m not a surgeon 🤦♂️)
I’m a new member so I’ll do my best to keep up-to-date on this particular thread as I am very curious as to why this is happening.
I have turned off all the monitoring sensors (12/27/2022 @ 10:45pm) to see if this helps, but I will continue to wear the watch as I normally do to rule certain possible irritants out.
Looking at the pictures, it looks like you wear the watch on your left wrist in the standard fashion. There seems to be a "knubby" irritated spot on your wrist where the digital crown sits. There's no lights/sensors emanating from that spot of the watch, yet the irritation looks to be just as intense at that spot.
Turning off the sensors is a great way to eliminate a variable, so by all means, try that out.
I would suggest wearing the watch on your right hand with the sensors on for a while, just to rule anything out.
As for the hand washing, everyone washes their hands differently. I too thought that there's no way it was related because I'm not in the habit of washing all the way up to my wrists. But lo and behold, suds do get a around and that's what it was for my issues. I'm much more careful to not get any suds under my watch and if I do, I simply rinse underneath and suffer a wet watchband for a little bit. Not a big deal considering the alternative is a really annoying rash.
Good luck. If you can, keep us all posted on your learnings.
