Have had the flu for a week and feel almost back to normal. noticed my throat still is scratchy and it feels like something is stuck in throat. stuck my finger in throat and theres a bump in the back of my throat, feels like a mouth ulcer. causes?

Doctor can evaluate: Throat symptoms can be from a strep infection (antibiotics are needed), a cold or the flu (antibiotics usually not needed), or from another cause such as allergies, irritants, other viruses, etc... A person may see a doctor if throat symptoms are bothersome, recurrent, or don't go away quickly. One's doctor can examine. Of course, having the flu does not mean a person cannot catch something else.
