My last dialation was Dec 2016. The previous one was six months prior to December. By Feb 2017 I was coughing and feeling like I could not get air at times. I was pannicking as it was way to soon. Decided to see an Allergy doctor hoping I had asthma or allergies making the situation worse. Allergy test revealed no allergies, no asthma. But instead of stopping there the allergy doctor tested my acid reflex left and felt that even though I was taking Ranidine at night that I needed to be placed on Omopropozle 40mg morning and night for one month to see if it helped the drainage which was causing the cough and mucous plugging my Trachea. He also placed me on two different nasal sprays 1)Azelastine HCI 2)FluticasonePropionate 50 mg which allowed me instantly to break a many year nose spray addiction. I between to breathe a lot better and had fewer coughing spells. Later reduced the Omopropozle 40 mg in the mornings. He explained that acid reflux results in much more mucous drainage. I also took note of a post from this website where somone was told to do "huffing" instead of coughing to unstop the plug in the trachea and explained how. It has proven very effective in spite of the fact it sometimes takes 30 minutes to get relief. Immediately when I "huff" or cough out the mucous plug I feel so much better for a good while. Now I only have around 4 episodes per day and I am not as short winded and breathe much better. Hopefully I will may it a lot long now between dialations. Whatever helps I am willing to try. I am looking forward to the conference June 2-4.
