I am a 63 YO male who smoked cigarettes for 42 years. I quit smoking in January 2015 prior to a major surgery. Prior to quitting I always had problems with my sinuses. Deviated nasal septum has been the major cause. I knew something else was affecting me more so as I started to wheeze occasionally. I took a spirometry test in 2012 and 2014. According to the technicians (not a doctor) they felt the amount I smoked, age, race, weight and gender that my breathing was pretty darn good. I bought an oximeter to just check my own O2 levels whenever I had shortness of breath. My actual readings are 98 and 97 most of the time that I feel like I have shortness of breath. I have had allergy tests done and know the triggers for my allergies. Mold is a big trigger and the last few days it has been very heavy. Suffice to say I feel short of breath. The doctor has given me albeutrol (spelling), but haven't noticed any real results from it. I do not do well with many of the antihistamines because of the side effects of them. I have not been officially told that I have COPD and CT scan of chest and there were several subpleural apial blebs. I guess if it was really bad news my doctor would have said something. I have had numerous issues over the years with my gut and was told I may have an IBS issue. I have slight anemia but they haven't been able to locate the bleed. I have had endoscopy, colonoscopy etc. My surgeon for an operation (hip replacement) said the anemia is borderline 10.7 out of 11. Of course this doesn't mean anything to me. I read a post where someone stated that there shortness of breath was from his Hiatus Hernia of which I do have as well and have had since I was diagnosed in my outgoing military retirement physical and never had shortness of breath from it. I really do not know what is causing my shortness of breath and will see my doctor next week. I don't know if I should be using the rescue inhaler if my O2 levels are typically 97 or 98 even when I exercise. I don't have high blood pressure. I am overweight 167 pounds and I am 5 foot 7 inches. The weight of course is in the gut. I stopped drinking alcohol in 2010. I am congested daily and do use Flonase, a steam inhaler and Mucinex and all of them give me relief. Is it allergies or COPD? Sorry for the long post. Any comments are appreciated.
