I Have A Constant Feeling Of A Lump On The

I have a constant feeling of a lump on the left side of my throat. It makes me feel (for lack of better term) gaggy. It is extremely annoying and upsetting. I cannot palpate a lump or anything. I do not have indigestion or heartburn that would make me feel that it is acid reflux, etc. I am very concerned and don't know what to do. Is this something that needs seen ASAP or just at some point in the future. I almost feels like my esophagus is "out of place". Should I be concerned enough to see a physician at the first of the week?
