I eat. hot food and i have a bump in my mouth at the upper cheek when i prick it with my hand it started to bleed .had no pain until i start messing with it is it serious i need help.wat can it be?

Bump on cheek: Sometimes heat can soften up an infection, causing it to come to a head at the surface of the skin. This leads to draining, especialy if you pick at it. This is called a fistula and could be an infection making it a serious matter that may require some treatment, and or an antibiotic perscription. See a dentist soon before it starts hurting. Treatment is always easier sooner rather then later.

Dont mess with it: It seems you sustain a blister due very hot food. Opening will expose raw surface that will bleed and hurt. Avoid extremly hot fluids or food.

See a dentist: It's possibly just the opening of the salivary gland but i recommend not picking at it and seeing your dentist to evaluate and tell you what it is.
