I took a benzetacil, do I need to continue amoxicillin?

I was taking amoxilin for 3 days and was not solving my throat pain, it was very inflamed with a lot of pus. I went to the hospital today and the doctor prescribed me an injection of benzetacil. Do I need to continue taking amoxicillin?
Expert answer:

Perhaps. Everything depends on what your doctor instructed you to do.
