Feeling mucus in my chest ?

So my family was sick around Memorial Day and it was an awful virus. Finally cleared up and I kept debating if I had a sinus infection because it was coughing out and blowing out green/orange/brown for a long time. It finally seemed to clear out but I am been exhausted big time. Just feel weak and tired. Yesterday my chest was hurting a bit feeling right and when I’d breathe I could feel or taste mucus in my chest (kind of hard to explain). This morning I don’t feel it as much so far. Debating if it’s a weird fluke or if I should go in to be checked. Thoughts?
