Been sick for a while, difficulty swallowing?

so i had what i think was a little bit of a cold a week ago. i lost my voice, was coughing and very mucus-ey. my nose was also stuffy. now all the other symptoms are gone but i am having difficulty swallowing. it is worst in the morning or at night but still noticeable during the day. it isnt effecting my activity at all tho. i am still able to play soccer and run around at the beach like normal. i was just wondering what i should do to help it or what it is. stuff like that.
