Suggest Treatment For Persistent Throat Infection

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 cases usually doesn t show up as anything on throat cultures
