I have had Air Hunger for the last 6 months. It started as not being so bad and I thought I had it licked but it is getting worse now the winter has set in. My doc believed it's stress but I've been on stress meds for years. He is now having me go to a Pulmonologist and I will be taking a series of lung tests and chest x-rays to determine if there is an issue with my lungs. Another interesting issue that he thinks may be related to this problem is a build up of carbon dioxide in the lungs which could be caused by Sleep Apnea. He has perscribed a sleep test which I will be getting in the next several weeks. My doctor had this problem himself when he was in college and he told me it just went away on its own, so my doc is sensitive to what I'm going through.
