I took two types of medications with acetaminophen without knowing to stop a fever and sore throat and now i have small little lumps under my lip?

Oral surgeon: Hard to say without examining you. See an oral surgeon to find out what the problem is

Canker sores: is the most common oral lesions. In some instances, they can be a sign of other conditions affecting the body (e.g. fever). Most ulcers, infections will clear up by themselves within a week or two. You should see your GP if the ulcer gets worse or lasts for longer than 2 weeks.
