This may be a new concept for you but I assure you that it is not a new concept for me.
Yes, standing still causes horrible symptoms the next day. I know about this on a visceral level because I was forced to stand still for the tilt table test (also called head-up tilt). I felt like I had been run over by a truck the next day.
I'm sure it's not intentional but many of the phrases in your posts make it sound like this is a brand new concept for everyone. It is not.
If you had said, "
I did not make the connection between being upright and becoming ill the next day" then that would have been clear. If you had said, "
some people do not make the connection between being upright and becoming ill the next day" then that's also true. And if you were to say, "
many doctors do not make the connection between being upright and becoming ill the next day" then I would also agree. Doctors are often ignorant about Orthostatic Intolerance (POTS/NMH).
But when you say "
no one makes the connection between being upright and becoming ill the next day" then I must politely disagree.
Lots of doctors doing medical research, including the Johns Hopkins folks who published a paper back in 1995, have pointed out this connection (symptoms lasting 24-72 hours after NMH or POTS triggers -- standing is one of those triggers). After my first tilt table test (back in 1995) I got a "crash course" (bad pun
) on this connection between standing and a crash on the next day. And in the years between 1995 and today, quite a few other patients have made this same discovery.
I hope this makes sense and does not sound too nit picky. I just think it's important that we don't invalidate the experience of all those patients who really do understand this connection between standing and feeling crappy the next day.
Again, I'm so sorry that your doctors did not help you to see this connection earlier.
Edited to add: I'm not trying to say that standing too much is the only reason that someone might "crash" the next day. But it is a well known reason for a crash. It's not something brand new.
