i had an endoscopy last week, my throat was a little sore afterwards but nothing too noticeable. for a few days after i felt fine just a tickle in my throat, the tickly quickly became a bad cough. for 3 days i felt exhaused and slept a lot, the exhaustion seems to have passed but the coughing has not. my throat does not feel sore until i cough, and very little mucus is coming up. ive tried everything from neo citron, nyquit, robitusson, buckleys, halls, cepacl, teas, honey, all these have either no effect of very short relief.
is it possible i got some sort of infection? and should i wait longer or see a doctor now?
