STD orrrr just sore throat

Kennedy

Hi so last saturday i gave this guy head and he said that he was clean. (sometimes they lie) but two days ago my throat started hurting and this morning i have white dots on my tonsils. now idk if it could be an std or a result of me sleeping in the heat for the last couple of days. usually i get sick from sleeping in the heat but i don’t think i ever had white dots on my tonsils and i do kinda feel it in my chest. can i have someone’s thoughts?
