The doctors tell me my chiari isn't bad enough to operate,it is about a 5 " ,my symptoms are 24 hour headaches,right side numbness sometimes,tingling face,right groin pain,vertigo,severe migraines where i cant walk,or talk.changes in weather hurt me bad,no short term memory hardly,and i've probably forgotten something,what are the symptoms for a 7 or a 8",i can't imagine it getting much worse,it's hard enough now.what will it take for the dr to say ,ok we'll fix it now? if they had to live like this everyday,they would want it fixed now!
