Couple weeks back had sore throat got meds and it went away then about 3 weeks later I have what feels like something flopping around in my throat, constantly need to clear throat, sometimes it will interfere with my vocal cords. My throat isn t sore, at night I can feel this flap fall to one side of my throat or the other depending on what side I am laying on. Is this something that will go away with time, is it another infection. Sometimes my sinuses are sore, but there is no apparent drainage, what do you think?
