It has been a busy morning. Very good news and bad news. Test results for Covid-19 are negative so that is awesome. However I had a video consult with my specialist this morning and it would seem the symptom's I have are consistent with Pericarditis.
Congrats on testing negative. I had to look up the other thing but it sounds like the lesser of the two in most cases. Not great news, of course, but hopefully less awful than Covid in your situation. At least now you know what you have to deal with. Good luck with it all.
