I have a kidney infection & would like to know if it will just go away. My doc also said I have blood in my urine as well. Is that from the infection.

Kidney infection. Usually true kidney infections don't go away on their own without treatment (antibiotics). Sometimes people have to be hospitalized for intravenous antibiotics for a couple days. Blood in the urine is common with bladder infections. Follow your doctor's advice, and take the medicine they recommended.
