A boil.
If the child IS pissing blood and puss, then this kid is messed up.
If the reason for the puss is still there it will keep reappearing.
That's never a good thing. Go see a dermatologist right away. You may have "Hidradenitis suppurativa."
go get some puss
It doesn't...that's a myth. Blood doesn't boil in space.
No!puss is simply one way the body sends bacteria out of the body.If puss is coming out of a bruise/scab its a good thing,it means your getting better.
white blood cells form puss and the puss helps protect until skin grows
Puss is caused by an infection where the body is actively attempting to fight it off. This microscopic war results in massive amounts of dead bacteria and white blood cells which cause puss.
White blood cells make puss to protect the body slowing down the blood
yes
Your mouth could possibly have a very large infected boil in it. That is disgusting btw.
