Dealing with Joint Pain and POTS: Seeking Help and Overcoming Stigma

I've been experiencing so much joint pain recently, and on top of it, my pots seems to be getting worse. I'm having such a hard time standing up. I want to find things that help, but it's so hard. I've tried adjusting my diet to add more salt and electrolytes, and it hasn't helped enough. I've tried compression socks, again, without any luck. I want to look into mobility aids, but I'm not sure where to start. and, even if I find one that helps, I'm not sure how to get past the stigma. I know my family wouldn't understand. so how do i find one that helps, but also, how do I get myself to actually use it?
