Getting scared

So I have tonsillitis or so that’s what the nurses said after giving me a throat swob ( I also have thyroid problems) they gave me antibiotics ( amoxicillin) But Before that I took some Doxycycline ( which made me feel worse . Now since taking the amoxicillin I can’t say I feel better, I’m still weak , one side of my arm feels like it’s falling asleep sometimes even when I don’t lay on it and now I have this rash on my chin alittle on my lips and under my eye ( not horrible or painful but idk what to do , should I stop taking the amoxicillin also idk if it’s the new pills , or the ones before but I’m clearly having an allergic reaction to something 😩 help . I swear I was fine before 😢
