One example of those who benefit from having their tonsils removed is psoriasis sufferers. In psoriasis, an overreaction of the immune system causes itchy skin lesions—often starting at the head—and painful inflammation of the joints. Psoriasis patients also have an above-average vulnerability to sore throats. One possible factor in this is bacteria, which can hide in the tonsils for long periods of time and needle the immune system from there.
