@BayesForDays ugggh, sympathies. it colored my experience and life for months and months. I mean I'm glad that you got some things ruled out but it's awful to have no answer. For me I think it was deeply related to some kind of small airways issue (maybe airways + inflammation idk, respiratory stuff is like SUPER complicated and SO hard to get care for), but didn't 'present' like asthma, kicked up a lot after talking. Just had to heal over time. Was also very unpredictable as it healed!
