In Chiari the CSF fluid is not allowed to "percolate" properly around the spine- the tonsils keep it from flowing. If your tonsils are not low enough to present a problem, I would search elsewhere. There definately is a problem if you are having headaches, we just need to find out what is causing them. Press your doctor to see what could be the problem. Keep a "headache diary". Write down the date, the time of headace, what you were doing, what you ate that day, pain level, what you did to ease the pain, and when it went away- if it did. Take this info to your doctor the next time you go and keep it up until someone sees there is a problem! This is how my pediatrician found my daughter's Chiari and she said this was the information needed to help determine exactly what was wrong.

Hope this helps,
