You are right.Covid did trigger it.I am in bad shape and I feel bad that you are going through the same thing.I have lost strength in the trunk of my body along with diaphram/sternum.Even if I had to throw up I could not.I thunk it is the loss of strength and vagus nerve damage.The neurologists I have talked to have never heard of such a thing.I barely have a gag reflex anymore.At the beginning I felt like a human vegetable.I could not swallow,go to the bathroon,sleep.I did have them test for Epstein Barr and my titters were extremely high.I know that before I was diagnosed with Hashimito's that is all that could find was elevated Epstein Barr titters.My neurologist is sending me to a team of neuromuscular doctors since he can't figure out what is wrong.I am praying for you and your Fiance.It is not fair that we have to go through this.I was only on the steroids for a very short amount of time since my primary was not exactly sure what I had,but It did give me strength.During that time I thought it was the end for me.I am just wondering if Ivig infusions could possibly help us.I will let you know if I hear on any new possible treatments.
