My 14 year old gets sore throat sometimes, once every 4-5 months or so. My MIL insists it's tonsilitus but tbh I don't trust her medical judgement. I used to get tonsilitus a lot and had mine taken out. My tonsils always went white when they are infected as well as swollen. At the moment one of ds tonsils looks a bit swollen and red but the other one looks normal. He also has mild cold symptoms. Is this tonsilitus or is he just fighting off a cold?
