A little history - mine goes back 4 generations, that we know of. My grandmother we are quit certain had POTS and EDS. My mom had EDS and MCAS. My sister has severe CFS and is in most all the research studies that are in progress, right now. She also has severe OI (orthostatic intolerance) to the point of her heart stopping on her tilt table test - 3 minutes into the test. Her kids have EDS, MCAS, and POTS. I have all three of those things and many autoimmune problems - including hypogamaglobulinemia. So you see it can run in families. And like you, my sister had anorexia. Our family has been asked to be in the genetic study that is going on for CFS. The boys are not yet old enough for consent and so far, we don't have approval for them to be accepted yet.
There also are methylation issues involved in our family. MTHFR and other mutations involved in this process. This would be worth taking a look at. Treatment fory mutations have helped me alot. This was also a family issue. The child born before me had spina bifida. A sign of Folate methylation dysfunction.
If we stand you will see us dance. We move around, sway and just generally can't stand still. We have to keep our blood moving while upright. You may see us fidget while sitting too. The leg shake, tapping feet, fidget. Again, us compensating for blood flow issues.
I feel there is also issues with low testosterone for guys. Many of us POTS girls have had endometrosis and that is thought to be an estrogen dominent issue. (Has the balance between testosterone to estrogen been checked?)

Issie your family is sooo interesting. I've gotta think they are a gold mine for researchers.
I definitely dance around when I stand...I NEVER stand still - always moving. When I talk on the phone when I'm standing I have to walk around. I think I'm trying to get blood to my brain...
It's amazing how complex all this is...
