Chest congestion, sinus congestion, inner ear canal has fluid moving around.

My immune system is deficient in the 1gG3 classification. Currently, I cough and have to hold my chest because of the pain. I seem to be on a 3-4 week cycle of getting sick. I call my asthma doctor who prescribes an antibiotic over the internet. I had this 3 weeks ago but it was better for a week or so after an antibiotic and prednizone. Getting into the doctor takes days and I don’t trust the urgent care facilities. The doctors seem to be inexperienced. Should I go to the emergency room this time? How do I know if I am in real danger of the congestion affecting my ability to live?
