It's a funny thing that I never see that a doctor or vet could get ailments or conditions but of course.....they do! I have same. All happened in 2020 along with Tinnitus Pericarditis IBS Under Active Thyroid Dysmotility Osophaegus. You couldn't make it up. I think it's weird it happened all at same time. The virus I feel caused it all but no tests then so no diagnosis save multi symptoms. Pericarditis gone now but have supraventricular ectopic heart beat! Tell me do animals get all this?
