Hi I Thought I Had Cold Or Sinusitis. So I

Hi I thought I had cold or sinusitis. So I called dr. But couldn't get appointment till next week so they offered to call in Prescription for antibiotc. They did and it's azithromycin 25mg. Dose pack. Today will be my last dose. However I had been taking mucinex-DM before to get some of the mucus out. I'm still having some hearing problem from the pressure and my ear is now leaking liquid . ? Oh I had fever. It's gone. I want know should I go back to mucinex-DM to clear my ear. I have had ear drum reconstruction many times. As a kid. I'm 57 yrs old now.
