“How do you treat chronic tonsillitis in adults?”

First you have to ask yourself how much of a problem is this and how does it affect me. A chronic problem would be three or more episodes in a season {fall through spring}. If this was a problem year after year then I would want you to consider a tonsillectomy. A tonsillectomy is not an easy procedure for an adult but it is the only way to resolve your problem.
