I don't know about your state, but it is in mine. Check the actual text of the order from your governor/county judge/mayor. In my state, no one is allowed (violation of HIPAA--federal law) to require explanation, documentation, or proof of your medical exemption. I'm RARELY asked to put on a mask now, and when they do, I simply smile sweetly and say, "Thanks, but I have a medical exemption." If for some reason they don't know their stuff and they ask for explanation (they haven't so far), I would simply smile sweetly again and say, "I'm not comfortable sharing my private medical information with strangers." If they REALLY push it, I'll pull out my phone and show them the relevant section of the governor's order stating that they're not allowed to require documentation or explanation. The less you draw attention to yourself (with other actions/clothing/words), the less likely people will even notice you're not wearing a mask, and even if they do, they will likely not say anything unless they're a Karen/Kevin.

You could have trouble breathing with it on (doesn't everyone?). You could have already had COVID and now be immune. There doesn't even have to be a medical diagnosis by a medical professional.
