In this area encircled in yellow colour, there is a greyish/whitish bump. I had throat infection last week, took roxid and it did not go away. I went to ent yesterday and she gave me cefpodem 200, montek lc. My symptoms are cough sometimes dry, sometimes wet, when i swallow i feel a sharp cut like sensation on my tonsil.. But i am still worried if it will not go away :(. Is that a bacterial or fungal infection?
