Just recovered from a cold now the left side of my throat is scratchy and feels like something is blocking it.

Doctor can evaluate: Throat symptoms can be from strep throat (antibiotics are needed), a cold or mild flu (antibiotics are not used), or from another cause such as allergies or irritants. Usually, a person sees the doctor if the throat symptom is bothersome, recurrent, or doesn't go away in a day or two (mainly to check for strep). A patient can have a cold (viral) and strep throat (bacterial) at the same time.
