He acts so normal other than those few things, that you would just assume they are growing pains, like I did when he first started having them.
During the attacks he doesn't gain weight
, and last year actually lost weight
. Also, for the week surrounding the 24-72 hour attack he turns into Uncle Fester, extremely pale and dark circles around his eyes. The attacks get longer the higher the fever becomes, so the first one will be about 24 hours, and then 48 and then 72 and so forth.
