Apple Watch Sensor Burns

I have had my watch for 9 months and about 3 weeks ago, I started getting irritation that turned into blisters. I stopped wearing the watch immediately. Then next morning it was so enflamed, and swollen, I wore an ice pack. I thought at first it was dermatitis and started using over the counter creams and Benedryl. I also cleaned the watch, changed the band. It started to get worse, like it was a chemical burn. I talked to my friend (a pharmacist), and some of my colleagues (I’m a home health nurse), and they all thought it looked more like a bad sunburn. I wanted to go to my dr but he was out of town for the holidays, and the instacare was full of sick people with a 2 hour wait, so I gave up and continued to treat on my own. I put a burn poultice on it, and . It stopped blistering. I has now been a week since I started treating it as a burn, and it’s finally healing, but is still painful. I decided to try using the watch on my other wrist, because I use the watch all the time for work. After 1 day I started feeling a deep itching/burning where the watch base sits. It’s a little red, but it feels deep. I called Apple support last night and sent them pictures. They are supposed to get back on Friday. From what I have read here, it happened to some right after an update, and I now remember I updated my watch about the time it happened. Hopefully I have better luck that some of you with Apple. I just want my watch fixed.
