Well, I am not a medical doctor, but I know that you can hear breathing problems in the throat with a stethoscope . . .. for example, if you have phlegm in the throat (usually the result of an infection) then the breathing will sound different to a trained practitioner than a throat without phlegm . . . if you have allergies, that also will affect your breathing . . . since this is your old doctor and he knows of your health concerns, I would trust him . . . if he was checking your chest, then he was checking your heart also . . . so, rest assured that you are doing fine . . . .by the way, if he checked your oxygen level, etc., then he did a very good job to make sure . . . .if he prescribed you antibiotics for the throat infection, make sure you take them all and don't stop until the last one is in you . . . otherwise, do what Granma always said . . .drink plenty of fluids, get rest, and eat lightly some good foods . . .take care, KC
p.s. if you are on antibiotics, then you make want to eat some probiotic yogurt to help maintain the good bacteria in your GI tract . . . .
