Can Amoxicillin Be Taken For Fever And Sore Throat?

hi, i'm living on an island called morro de sao paolo in brasil, for the last 10 days i have been with a high fever chills sore throat headache and earache. I took paracetamol 750mg for a week and the fever went down and i feel a it better, i now have a bad cough and am feeling tired and run down all the time. i had very bad diareha for 2 days last week too. I have taken an amoxcill 500mg can i carry on taking them and what dosage.

Thanks Celine
