My tonsils are bleeding, swollen, and have puss coming from them.

Acute tonsillitis : Tonsils are like sponges in the back of the throat. Just like sponges they have pockets where things can accumulate. Sometimes this is bacteria. The bleeding is caused by little infections pushing out debris like abscesses rupturing. It is important to check to see if it is a strep infection as this can effect your skin, heart and kidneys.
