Thank you for your query.
At the outset let me tell you that chicken pox
usually comes once and does not recur. Secondly chicken pox rash
is mostly in the peripheries and very few lesions in the torso region. Thirdly when the chicken pox rash starts appearing the fever
usually starts coming down. Since the doctors are suggesting various diagnosis like eczema
, and molloscum it is better to consult a dermatologist
It is not possible to give any suggestion without having a look at the lesions.
I hope I have answered your query to your satisfaction.
Wishing your son a speedy recovery.
