Hi and welcome to the Chiari forum.
If it were me, I would say yes, not to allow the wrestling as it can make symptoms worse....and this can be hereditary so u may want to get a MRI too.
There are Chiari Drs at CC, and I do not know what part of Ohio that is, but there is a Dr in Pittsburgh, PA too....
Use the list of Drs in our Health Pages to research as to which ones treat children and also work with ur ins,
Educate urself on Chiari and chiari related conditions as it is very important that he is checked for all related issues as they can play a role in how he would feel and heal if he were a surgical candidate.
U ask the questions and we will do our best to help educate u : )
