About a week ago I came down with what I think was a severe sinus infection. Everything went away, except for what seems like excessive mucus in my throat and a weird sensation like something is stuff in my throat (the placement seems to move form one side of my throat to the other, and occassionally seems to be accompanied by ear aches on the same side). As long as I take Mucinex I seem fine, but as soon as I miss a dose it seems like lump, etc come back. Thanks.
