I had the same issue when I started PT. I had COVID February 2020. My Pulmonary spec, on Monday just told me it was all in my head, I was depressed and needed alot of heavy cardio PT! My Amyloidosis returned and spread, had surgery and going to sppeech PT, airway compromised. I have GI issues many procedures and test and on a soft/pureed diet, Kidney issues with HBP, and an MRI showed compression of C5 and C5. The list goes on and on, but I'm just depressed and need cardio. At lest you go validation and empathy. Sorry for your Long Term effects, but maybe go slow and can find a good Pulmonary Speciality and do Pulmonary Rehab, something mine never recommended!
