Infected Tonsils?

Patient: I’ve been having a lot of stomach pain recently in the past couple weeks, however i think its due to the fact i had a really sore throat with raw tonsils i never got checked for a couple months and now some infection is traveling through my body making me feel sick and sharp pains in stomach and chest. Any idea of what you think could be happening to me? also some small hard lumps directly under my tonsils on both sides.
