Hi and welcome to the Chiari forum.
I am so sorry ur little guy has had so many surgeries and is dealing with so much already in his young life.
Many if us do have sleeping issues....has he been tested for sleep apnea?
U can have a sleep study done in ur home, instead of a clinic....research NovaSom....
I had swallowing issues that did resolve post op .....but with his Aarskog-Scott condition, I would not know how u can tell what is from which...as he has joint laxity and many with Chiari also have it as they also have EDS which is related and causes the same issue....
I would strongly suggest finding a Chiari specialist to help u decide if surgery is going to help and answer some of ur concerns...as there is so much going on with him....not all Drs are capable to knowing what may or may not help....and if his Drs are not true Chiari specialists they may not know how to advise u.
A NS is not the only thing to look for when seeking help with Chiari....u want one that treats and researches Chiari and ALL related conditions.
Chiari symptoms do cycle, so having good and bad days is typical.....
Does he wear a helmet ? it may help until he gets help with his balance and help with the concussions,.....
With joints that are lax, u can have pain, pain makes u tired....I had periods where all I wanted to do was sleep....plus he is growing....that has got to be tiring for him. But do have a sleep study done too.
we do have a list of Drs for u to use to research....
