Chronic sore throat. That chronic cas!

So about 4 months ago i had strep throat infection and i had yellow or white thrush on my uvula and my primary prescribed me penicillin which made a lot of improvement in a short amount of time but i only managed to finish maybe half of the treatment due to dirrhhea and some of the infection of was still on my uvula when i stopped the treatment but still the rest still went away on its own, but now i've had these tiny pimple like lesions on my pharynx for the past 2 months it's doesn't hurt or bother me at all it's just once in awhile it feels like a super mild sore throat and it goes away and you don't even notice it. i'm wondering if its chronic sore throat and maybe the strep bacteria caused it because i never finished my antibiotics. i'm going to show you a picture please let me know what i should do and what you think how i should treat it. my primary is kind of dismissing and took a throat culture still waiting on those results but i've read that chronic cas
