Need advice on appointments

For those of you who have been in this situation, what do you do when you need to get hold of a doctor and simply can't?

Looking back at certain symptoms, primarily ones need a urologist, they began to get really bad after my Crohn's did. Before I was even diagnosed with Crohn's I had a really severe yeast infection, given the proper medicine, and thought (hah!) that that was the end of it. Only know it's no yeast infection, and it's not an infection at all apparently. I finally gave in to go to the ER because it's getting rather painful, and I can't go anywhere except for what is absolutely necessary e.g. the hospital.

I told them what was going on, that it's something that has come before, gone away, then come back with a vengeance several times. They took a urine sample, told me there was nothing wrong, and sent me on my way with a prescription for antibiotics. Which I have tried every time it comes to this. Which don't work. It always comes back.

But to the main point:
I'm trying to get a hold of several different doctors (urologist, possibly new GI for another opinion, neurologist, etc.), and I can't. I call and their signal is busy, they don't pick up, or they refer me to an audio message saying "call this number to get a hold of so and so!!"
The funny part? That IS the number I called to get a hold of so and so. It just refers me to phone numbers that don't do anything.
I'm not going into the ER again because it obviously isn't going to bring results.

What on earth do you do? Is it going to have to be that I have to go down to the hospital itself and demand an appointment? There aren't any other numbers to call. Would it be wrong to call my GI and ask to see if he could get an appointment elsewhere? Without mentioning he's being overlooked temporarily for another doctor...

I've never had this difficult of a time making an appointment before. I can't be stuck out of state after this weekend with a wide range of untreated problems. There's no point in going if I'm just going to be stuck in the bathroom the whole time.

I pressed the number for those options, but it just said invalid extension...

I finally got a hold of someone. They can't make an appointment for me in spite of the fact that I can't leave the house and, most of the time, the bathroom. I cannot sleep because of this gragaga SO GRUMPY.

I finally gave in, got in contact with my GI's nurse, and she said she'll see what she can do after she heard no one else was doing anything except 1) urine test and antibiotics or 2) nothing.

This is seriously like having a severe Crohn's flareup but switched around. Cystex stopped working too so...

I just don't want to be rude to the person getting me into the office. Have any of you ever just lost it and got in that way? I feel like I'm losing my mind with all of these problems here!! Little things are adding up, and I have to urinate every 5 seconds.

Yes, I whine and complain...very grumpy today...

Tears have worked for me as well. Sobbing on the phone when you are normally a rational human being seems to get someone's attention. I've also dropped in once before. Of course they hate that but I said my cell phone wasn't working and I happened to be in town anyway so I figured I'd come in and see if they could squeeze me in. They did. Do you have urgent care? (A walk in that is a step below ER?)
