Hi NEVER apologize for asking questions that is how you learn....and everyone else can as well ....not everyone is willing to ask every question they have, and so they don't get the help they need.
There are activities we are to avoid to help lessen or reduce flare ups....all we can do is try to relax since most times meds do not help.
Typically Chiari symptoms cycle.....so how we react to stress and how much we push ourselves can affect how we feel....so listen to your body, and if you need a link to the list let me know.
