Thank you to everyone for the responses! I'm taking notes and will be calling the university Monday. I bought my daughter some compression socks that haven't arrived yet. She's very sensory sensitive, so I'm not sure she'll be able to tolerate them. Also, I wasn't sure if the help they'd give would be canceled out by making her hot wearing them when it's 90 degrees outside. For dorm life, she's able to shower. I think she may need a tiny pedals-only, under-desk exercise option vs her full-size recumbent bike, though.
I wish she were up to calling the university herself, but she seems to be having a medication reaction that started yesterday. She's been on buspirone and had just increased citalopram a couple of weeks ago, so she's now feeling the med change. The doctor we talked to agreed that tapering off the buspirone was a good idea. I just hope she's one that won't get withdrawal problems. And that her dysautonomia symptoms won't get worse.
