Hi I am so happy to hear that my message had an impact on you, it helps me just as much to think that I am capable of offering support to someone when we all feel we are struggling to help ourselves, it boosts my strength and motivation so thank you too!
I am sorry to say that as I live in England I can't advise you on financial issues, but there are many users of this site that have experience with this as well as indentifying doctors in their area. I am aware however, that companies like "Kaiser" are profit orientated and as a result, seek to deny health care where possible in order to maximise their profits. If you request health care, it is basically their job to come up with a reason why they shouldn't have to pay out. My heart goes out to you and everyone else facing this additional barrier to getting the right treatment.
In my last message I mentioned that a spinal syrinx is a common complication of CM due to fluid being obstucted in the spinal cord. This happens because the bit of brain that has herniated blocks the passage of fluid that normally flows around the brain and spine. When the obstruction causes a build up of fluid on the other side (as in the brain side not the spine side) then this is called HYDROCEPHALUS.
I have learnt from experience that CM is a condition where the patient really needs to take control and not be deterred when offered what you feel to be wrong information. If I were you I would write to every relevant person you can stressing that it is only a neurosurgeon with experience of CM that has the knowledge to comment on your condition. Even if there is no treatment to be done, IT IS ONLY THE NEUROSURGEON WHO CAN DECIDE THIS, even neurologists won't pretend to know more about it than they do!
As I say, there are others on this site with better info on how to deal with SSDI etc. For now maybe have a look at some pages set up to help.

This site gives you the option to contact a surgeon directly and request an appointment. It is so, so important to see specialists, everyone I speak to with CM tells the same story of being told "you're fine" by doctors which makes it even harder to cope. The web site above says that even if the CM is discovered by accident, the patient must see a neurosurgeon. No one should be stopping you from seeing the right specialist.
The surgeon will need to see an MRI of the head and cervical spine. If possible a CINE MRI should be done which shows the flow of spinal fluid around the foramen magnum, which is the bit where the CM pokes out!
I will help however I can to make sure you get what you need, if the web sites about Chiari don't help you get any further, just ask and we will find another patient on this site who has been in your situation and found a way to cut through all the red tape! Try not to loose motivation, there is an endless source of help and support available through sites like this one, so it is never the end of the line. We all have different knowledge and abilities so between us can offer help with almost any aspect of CM.
Don't forget how much you have already accomplished, 3.5 years is no joke, be proud of your strength!
