It’s not an allergic reaction! There is no need to go to your Dr. It is 100% related to these Apple Watches!!! I don’t know why or what it is but there certainly seems to be a lot of people dealing with it!! APPLE DO SOMETHING ABOUT THIS ISSUE!!
Allergic reactions to the materials used with Apple Watch are fairly rare, but are possible.
Other reactions to other substances present (sweat, salts, bacteria, grit, and other such) can be more common.
I’d encourage a discussion with a medical provider for any skin reactions, as various skin reactions including urticaria and dermatitis or other reactions can look similar to the photos and descriptions posted. Rubbing, too, can cause irritation.
Some reactions can be minor and quickly resolve, others more serious. Severe allergic reactions can be fatal.
What has been shown looks less like the usual patterns of a thermal contact burn, but a medical provider will be a better judge of that. Contact your provider. Also contact Apple directly.
Here is what Apple suggests about this topic: Wearing your Apple Watch - Apple Support
Here is one of many case studies: https://www.sciencedirect.com/science/article/pii/S235224101630024X
TL;DR: Log feedback with or contact Apple, and also check with your medical provider.
