Well said. It doesn't matter what tests we do. There simply is nothing for us in this modern era medicine. There simply is no explanation for our symptoms. Nearly all the symptoms that we are going through are mysterious to the doctors. No diagnosis , no explanation , no understanding of the mechanism, no treatments, very little hope and support , nothing to look forward to in future, no assurance , totally un predictable and no timeline . on the contrary there is huge ignorance and lack of empathy by doctors. PCS is surely hell on earth! Sorry to be so negative but I am sick of this now
