I had a mild cold last week with a lot of phlegm, but the colds gone now, but for the last 4 days now i have?

a feeling of a lump in my throat. i thought it might be phlegm stuck there, i have taken medicines for it and pastilles but nothing has worked. i dont have a sore throat or anything and feel fine except for this lump. it's mostly worse at night. and i can't see anything in my throat. there is no pain. it doesnt cause any trouble with driking or eating, if anything it relieves it a bit. it just feels clogged.
