Hi...u nailed it just right...chiari does cycle, how long it cycles depends.....but I went long periods where I could tolerate the symptoms and the HA's...that went on for yrs.....but on and off I would have to go back to the Dr...it is bcuz of the way the symptoms cycle that Drs and even us chiarians find it diff to connect all the symptoms together.One of the major reasons it took yrs to get dx'd in my case.....
Most of us enjoy the down cycle when we r feeling good, knowing if we do too much, the up cycle of pain will return with a vengeance.
As Ray mentioned, u have to be careful with ur activities to help avoid certain positions and strains when possible to help lessen the pressure we feel.

In my experience the most symptoms of CM come in cycles. They can last for days or weeks, some symptoms like numbness are with me all the time. My balance is off most of the time but sometimes it gets much worse with vertigo & dizziness especially if I cant tired, I have problems sleeping, some times I cant sleep and other times I cant stay awake, this can last a few days or a few weeks.
When you bend down or strain, laugh, cough, sneeze this increases the CSF pressure and can cause problems.
