The Apple Watch Rash

I have a Series 9 Apple Watch. I've never had any skin conditions before. I never wear this watch to bed. I never shower with it or even wash my hands with it. I'm too nervous to cause any damage to it. I simply wear it during the day and more specifically for my workouts/fitness. Sometimes I even forget to wear it all day but I make sure to put it on for my workout. I wear my band loosely and I always clean it before going back on the charger. This rash is so bad and it burns. I've not worn it for days so the rash would heal, clean the back, clean the charger, I even clean the band despite the rash being right under the sensor area. It's such a shame to see all these posts of people who spent alot of money on a watch just for it to cause these itchy painful rashes. I hate that I spent so much to not even be able to wear my watch everyday. I've been sick for the past week and haven't been able to go to the gym so, no sweaty sensor, yet I still have a rash. I've only had the watch for 8 months. I wonder if they'd allow me to return it?
