Thank you so much! Its funny that you just wrote this. I just had an episode yesterday. I again went to the emergency room. I just bruised a rib playing tennis, I thought maybe it had something to do with my injury. My doctor told me to go to the ER. The rib may have punctured an organ. My once again crazy symptoms, rapid hearbeat, feeling like I was falling sideways, breaking out in a sweat etc. Many testd not a thing to do with my rib. Unfortunately it was my long covid again, I know the drill by now. The doctors in the ER looked at me like I was crazy once again. They also told me once again if it gets worse just come back. I think my neighbors which are also my friends are even starting to think I'm crazy they keep telling me I have anxiety. Unless you know someone with long covid or you were dealing with it you have no idea what we go through. I will take your advice as much as I want to hear the results it may help in the long run. Thank you so much for writing back I hope other people reading take the advice also. Take care of yourself.
