Thanks for your query.
His features do not suggest any risk of fluoride or sorbitol overdose.
There is no point in speculating, and we should wait till genetic test results are available.
Familial Mediterranean Fever
(FMF) is the most common periodic fever syndrome
Despite the fact that FMF is a genetic disease, a genetic mutation
is not found in all children with FMF. Therefore the diagnosis of FMF is still based on clinical signs.
FMF cannot be cured, but it can be well controlled with life-long use of colchicine
Hope I have answered your question.
Wish your son a good health.
