i have a hard knot in the back of my throat behind my ulva. It does not hurt but for a few months i have felt like i have a lump in my throat, much like the feeling of phlegm. I have noticed my voice has changed the last few months, kind of hoarse, not bad, though. Don t know if the knot has always been there and i just discovered it or what. How i found it was i felt like i had something hung in the back of my throat, so i stuck my finger back there and found the hard knot.
