I have this lump sensation in my throat that wont go away. it feels like something is slightly pressing on my windpipe/ thyroid. this started on the 27th and hasnt gone away,it just suddenly appeared, I was getting ready for a 2 day convention. I have had my thyroid checked and it is fine,even an x ray of my throat,nothing is there, could this be a possible viral or bacterial infection,I dont have a sore throat or pain just a lump in my throat that isnt there. or could it be globus pharyngeus?
