What can I take to relieve ear pressure? - ear pressure more condition_symptoms

Since November last year I had the constant pressure of the sinus / nasal congestion. It was also recently diagnosed with chronic sinusitis. Anyway, a few days ago my left ear started to hurt, and felt as an obstacle (liquid), although they also hear it outside.

I think my question is ... What can I do to relieve the pressure?
