Hi, I was treated for a severe sore throat a few weeks back, doc gave me an antibiotic as I still have my tonsils and I was pretty feverish, not high fever, lowgrade. Antibiotics cleared up throat but I was still quite fatigued and sickly for about two weeks. Fatigue is gone, I feel much better but I still have some slight soreness and phlegm (a little and it s clear) in my throat. Is it unusual to still have my throat somewhat sore. My voice is still not normal either.
