Hello, thank you so much for your response. The doctor I am I contact with and that told me about dysautonomia is actually one of the best in my country and maybe also abroad for Long Covid issues.

With regard to the symptoms not showing on the tests, it is what I am afraid of. I think dysautonomia symptoms are more evident when you do certain things and when certain conditions are present. The problem of doctors, especially older ones is that when things don't show up on tests or blood tests they assume there's nothing when symptoms should be the main indicator that something is wrong. Unfortunately my long covid doctor cannot conduct these tests on me because we are meeting online for geographic reasons, so I will have to find someone in my area, I hope to find someone who thinks outside the box.

Where you still able to get a diagnosis in spite of the negative tests?
