I've heard that some docs charge a 1 hour consult fee to fill out the FRC form.....that would probably cost a few hundred.

I "took the liberty" of filling out an RFC form myself to give them, to give them a better idea of what my capabilities are/or where at that time. That included that sometimes I could stand or walk for up to 1/2 hour, but sometimes I could only stand for a minute or two (just long enough to get into the bathroom). I could often sit for hours at a time, but many times for only a few minutes without having to lay down. I cannot go more than a few hours without feeling the need to lay down. If I do not have the opportunity to lay down when needed, my pain increases until that time when I can lay down. My docs could refer to my notes when they were completing the form if they desired.
