I posted this question on the Lyme board too. Looking for ideas. Does anyone have a GREATLY reduced lung capacity? I have been having trouble breathing, short of breath, airway constriction for a couple months. Went to my ENT yesterday. My airway is only 20%, not good. Did a Spirometry, wasn't good. Gave me inhaler of Proventil then repeated the Spirometry, still not good. Said these numbers would be typical of a 3 pack a day smoker. I quit in 1982 at age 24. My capacity is down 36%. Even using the inhaler my function only improved 3%, basically nothing. I feel like I can't breathe. I have not had Asthma previously and he is not saying I have Asthma now. Allergies yes. He showed a LOT of concern. Went today for a CT-Scan on my chest. Going tomorrow for a Barrium Swallow as I had a LOT of acid burns. More tests for Sleep again, later, but he wanted a look inside my chest first. I've had thyroid surgery twice because of Goiter causing trachael obstruction. Mine grew below my collarbone. It feels very similar. But, those times, my lung Spirometry was good. I'm trying to figure anything out that might be causing this, short of a mass in me. Don't want that. Have a couple ideas I will throw at him when I see him again next month. But does anyone have any thoughts on this? Thanks, and YES, prayer is welcome.
