in my area we also have a major shortage for pdocs, and mine just happens to be the most well-known in the city. for at least the past 3 years, i only see him once every 2 months, which is not enough...i now have a regular doctor helping me, but it's hard b/c as my doc says the pdocs are the experts in what we're going through...just think of all of the extra training/education they have.
i think that you should definitely still go to your pdoc. from my situation, every single appt i go to i have to think back to what's been going on and sometimes when i feel fine it feels like there's no point in going, but there definitely is. it will be good to discuss what you were feeling. i'm not sure if this is a relapse for you or if you have cycling or what, but it's important to keep the appt and talk about it for sure.
it's definitely frustrating to say the least when trying to get treatment (immediate) for our illness. and there's nothing any of us can really do about it, except go to the hospital and that's usually really traumatic for a lot of us i think.
anyway, hope i helped a little, take care of yourself, hope the stress stays away and you feel stable.
hugs and support all around
