Question about some sores and spotting on tonsils.?

Hey everyone, I've been having trouble with a post nasal drip lately. I know it's common to get a sore throat when you have PND, so I didn't think much of it, however today, about 3 or 4 days after the start of the PND I noticed I have some white spots on each of my tonsils and there are two lumps on the back of my throat near my tonsils which look irritated and inflamed. I recently quit smoking and it doesn't really appear to be any kind of tumor as the lumps are pretty uniform and localized, anybody know if allergy induced PND can be a cause for tonsil spotting or these lumps? Just want a general opinion before I go as far as to schedule a dr. appt. (I don't want to spend the money if it's just a general symptom of PND.) Anyways, any help at all is appreciated, Thanks!
