I'm not an anti vaccination activist OR a conspiracy theorist, but I think both COVID and the COVID vaccination have caused diaphragm paralysis in some people. Several of the 1,400 members on the facebook page for people with paralyzed diaphragms think this is what caused their paralyzed diaphragms. In addition the most prominent doctor in the world dealing with paralyzed diaphragms posted that he has treated a handful of patients where both sides of their diaphragms had become paralyzed due to COVID and/or the vaccine. Fortunately, all of them recovered over time.
