Is it possible that my rings are causing burns on my fingers?

Yes, it is possible for rings to cause burns on the fingers if they contain nickel, which can lead to a condition called contact dermatitis. It's important to identify and remove the cause of the irritation to allow the skin to heal. If you suspect that disinfectant may be the culprit, it's a good idea to remove your rings, allow the skin to heal, and try wearing them again later. When using disinfectant, make sure your hands are completely dry before putting your rings back on to prevent further irritation.
