As said above what size is your RTC what size home is he in and what are the water test resaults? and a pic would be very helpfull. And dose it look like vienes or strech marks or compleatly different again?
hey hun, he bumped anything or been picked on? could be burst blood vessels.
if it is u can just do the best with the norm. bump up temp and add salt.
most the time it is poss that they pull through.
pics will help though.
