Hi Pono, one of the things that stuck out to me was the Chiari? Have you ever had a follow up for that? I have syringomyelia, not chiari but alot of people have both. THere are so many symptoms that you list that many with chiari or SM also have troubles with.
One thing is that if you do have chiari you should not have chiropractic work done. The message board for ASAP is down right now but you can still read all about it at the site. The web site is at
http://www.asap.org/
Give it a look around and hopefully the message board will be fixed soon and you can get more information there. I am still learning myself but there are many there who know so much and are very helpful.
Hope you feel better soon...Sue
