Hi and welcome to the Chiari forum.
It is not something to be known just from the symptoms....you need to be seen by a Dr and have some testing....I see you also posted in some GI forums as well....so you do not have any idea what is wrong.
There is a stomach virus going around and you may have caught that, it can last a week or more....
Call your Dr and be seen....and let us know what you find out.
i got it checked today and it is stress induced. I basically have to make some changes and find some peace
Glad to hear you know what the cause of your symptoms is, and I pray you are able to relax and feel better.
