My tonsils were inflammated, what should i do with this?

By seeing the doctor: If a strep infection had increased the size of the tonsils, the doctor can treat with antibiotics. If a viral infection (such as mono) had enlarged the tonsils, the doctor may use a few days of prednisone. If the tonsils are always big, and the person has no problems from them, it may be ok to just wait. If tonsils cause breathing, swallowing, or sleeping issues, an ENT doctor might remove them.
