I Have Had A Raspy Voice Since February 2018 It

I have had a raspy voice since February 2018 it came about after having the Flu & Pneumonia in January. I do have a thyroid condition and have some systoms- coldness, depression, anxiety, weight gain, AFib,- I'm thinking Its allergies or my thyroid meds needs to be changed ? Maybe see an Specialist?
