Long COVID and presumed poor perfusion, no relief from fludrocortisone or midodrine

Summary

The user reported no relief at all from fludrocortisone 0.2 mg, midodrine 10 mg twice a day and salt plus water, taken for what they believed was poor perfusion despite no low blood pressure. Guanfacine 1 mg extended release for 25 days also yielded no results, and their catecholamines did not raise above the threshold for hyperPOTS. They did not describe how long they had been ill or how they were functioning overall.
