In Mid April I Was Very Sick. Most Likely Flu

In mid April i was very sick. Most likely flu but did not get tested. It was about 3 weeks that I had temps, cough achy joints and 2 days with no voice. Since that time I have had a cronic cough. No fever, no aches just a dry hacking cough. My throat feels raw at times. The coughdoesn't produce mucus but can be almost painful at times.

Any thoughts
