Thank you for the link. It is one of the things we considered. He has some of these symptoms but others don’t match. I will mention this possibility to my daughter again so she can ask the doctor.
As far as I am concerned, they should consider anything and everything until they can rule them out.
Praying for him and praying for you too. :) You’re obviously worried and I know how scary it is to have an ill child, especially not knowing what he has or how serious it could be.
The doctor’s won’t apply a test for Kawasaki - because one doesn’t exist. You need (as another freeper put it) a great hospital associated with a university to take the child to. They will do a better job of eliminating the other possibilities. Prayers up!
