I forgot to mention, I have POTS and I wear an abdominal binder which helps prevent me from passing out. This is not the most comfortable thing but it has made a big difference. You can also wear compression socks. I can't wear them due to having Neuropathy and the extreme form of Neuropathy, Chronic Regional Pain Syndrome, in my right foot and lower right leg. I can't stand anything tight on my right foot as is it sets off awful pain and nerve sensations. I got my abdominal binder on Amazon for around $20. This was recommended by one of the doctors I have seen at the Long COVID clinic where I am a patient. Also, I would not push yourself with physical activity. I pace myself and do 20 minutes of activity at a time. I made myself worse when I pushed myself. Good luck! Keep your chin up! Look forward to your June appointment. When things are at their worst, the only way to go is up. Things may never be the same again but there can be improvement. Then there can be new, even really small things, that can make you happy. And as I said in my last post, you have value. We all do.
