Dear Doctor, I am a 22 year old male, 6ft 1 inch and 12 and a half stone. I went to the doctor on Monday morning, now being wednesday night, with a lump on my throat. I was told it was an infected cyst and prescribed antibiotics (pencillin). The lump as now gone red, grown bigger, become harder and now excitibits pain. I have tomorrow and Friday treatments still to take. Is this normal?
