I Have Had A Cold And Sinus Congestion For About

I have had a cold and sinus congestion for about 6 weeks. The cough has cleared but my voice is still raspy at times. I was on antibiotics which did no good. I have been using nasal saline sprays to clear the congestion and eye drops. Yesterday I notived a dent on the lefy side if my forehead. The skin is irritated around it. Could this be related to mt ither symptoms.
