Welcome to the forum. No need to apologize for ranting. We all do our fair share of that here on an as needed basis. :-)
What you are experiencing is very frustrating. It is good that you will be seeing a new neurologist. You will want to get a copy of the films or CD, and the written report from the radiologist who read your MRI. Bring those with you to your new neuro. Now is a good time to get copies of all lab reports and any other testing you've had. Having those reports will come in handy. Good for you to know what tests have been done and to share with other doctors. Always keep a copy for yourself.
A couple of things come to mind while reading your post, mostly questions.
Do you know if your MRI was done using MS Protocol? The pictures or "slices" will be smaller than the usual MRI. Sometimes the strength of the machine can make a difference to see a lesion or not. Was Gadolinium contrast dye used? I remember being told that a microscopic lesion on the optic nerve can cause vision problems. I also remember how reds were washed out. The colors red and green annoyed me. It was bothersome at Christmastime with all those blinking red and green lights.
What did the neuro-opthomologist have to say? Did he suggest NMO?
With MS, it is common to worsen after the birth of a child. Not sure about other diseases.
Perhaps your new neurologist would be willing to MRI your cervical spine?
Have you been evaluated by a rheumatologist?
We have a great resource here in the Health Pages - upper right hand corner. Apparently, it is possible to have MS without visible lesions. I don't mean to say MS is what you have, but information is what you need right now.
