I have small bumps in my mouth that ache when I touch them with my tongue or eat. I also have a strep-like white area in the back roof of my mouth.?

See your Physician. Can be numerous things with other signs like fever you haven't mentioned.
Suspicious lesions. Any suspicious lesions in your mouth that do not resolve spontaneously need to be evaluated by a doctor. Inflammation, infection, and cancer are all possibilities depending on risk factors, symptoms, and exam/biopsy.
