I can certainly relate - we (fiance with LC)have been to so many doctors and tried so many things….. just resigned to the sad fact it may be the normal now - close to four years / have another “ 6 month checking “ with long COVID doctor tomorrow ( via zoom ) and I have no idea what we will even talk about ! Not looking forward to it -plus I contracted COVID before Thanksgiving and unwittingly passed it on to him - so this only put him back - I’m sorry for your frustration and dismay
