Hi, sinus infection for past week. Nasal irrigation helped, mucus clearer & congestion gone. Now left ear is clogged &left side of throat/ear is sore?

Great. you may want to continue the saline nasal washes, and salt water gargles in addition to pain killers and lots of fluids and rest, if no improvement in a day or so, see your doctor for possible need for Rx medications, good luck.
