Good Luck on the 13th....do keep us posted on what you find out.
Btw I'm in Dallas Tx I go to see a neurosurgeon that specializes in Chiari, Dr. Richard Jackson, on the 13th.
Oh wow really? The neurologist Dr. Motgi to be exact told me oh You'll be fine... He also gave me zoloft that I cannot take with tramadol which I use for pain. It can cause serotonin overdose!
Hi...11 mm's is the length of the herniation....there are 2 tonsils and generally they only list the longer of the 2.
Not knowing where you are located I am not sure where to steer you, but you will want a true Chiari specialist to help you as most Drs do not believe Chiari causes symptoms and consider it an incidental finding.....
Find a Dr that not only is familiar with Chiari but is well experienced it as well as with ALL related conditions too.
