Sinus Medication Solution

I have been treating a sinus infection for the last two weeks and have been to the doctor several times. My ears are clogged to the point of distracting me from my everyday life, I am dizzy and uncomfortable from all the pressure, and become carsick easily evem during short rides. I am taking pseudophedrine 60mg every 4-6 hours, and have completed an antibiotic treatment (azithromax for 5 days). What can I do?
