Post Sickness

About 3 weeks ago, I ended up sick, but for the last week, I've had no symptoms of the sickness. That being said, my voice at times sounds like it wants to cut out. Mostly anytime it does this, it feels like mucus on my cords. If I lightly clear my throat, it seems to fix it for a moment. Have I done something concerning to my voice, or do all singers get lingering mucus after sickness sometimes? Keep in mind I had no issues before getting sick. Hope this makes sense. Thanks.
