Hi and welcome to the Chiari forum.
I know having a condition like Chiari we do not think we are affected by it like some of the others we read about....but since it is a congenital condition we may have more going on then we realize since we have always had to deal with the symptoms and consider them "normal" until they worsen and then we begin to connect the dots and understand much of how we feel is not "normal" and symptoms of this condition. I am not aware of any meds that help as none helped me...I know avoiding some activities can help....and there are things we can do to help once the symptoms flare...are you interested in these type of things?
