Hello All,

I am a late 30s male and had post nasal drip for years and eventually a sore throat for many months.  Allergy tests confirmed I am allergic to various things and the initial spirometer put me at a 79 lung age with an FVC of 61% and an FEV1 of 62%.  I have been on some strong inhalers for several months and am now at a 72 year lung age with 70% FVC and an FEV1 of 68%.  My peak flow when I started was around 450 average and now it is up to 500 average.  Occasionally, I have asthma attacks where my peak flow goes down to around 390 or so and a rescue inhaler helps.  Other times (such as right now) I have a tightness in my sternum, feel like I can't take a full breath, but my peak flows are normal.  The spirometry report seems in indicate I have obstructive and restrictive lung issues.  The asthma/allergies seem to cause the obstructive but I don't know what is causing the restrictive as my chest x-ray a year ago was normal.  The restrictive can't take a full breath/tight chest feeling seems to mainly happen in the winter.  Any thoughts and what do people in the same situation do to relieve the tight chest/can't take a full breath issue?  The doctor was hoping me taking such strong inhalers that my situation would be somewhat reversible.  Going from 79 to 72 lung age is better but I guess not the greatest as I most likely have permanent damage from growing up with second hand smoke and animals (which I am allergic to).

    Based on my height, a high 600/low 700 peak flow would be normal for me but my average again is currently around 500.

      Thanks Nigel.  I don't feel like I have a chest infection so I am not sure what to do to relieve the tightness/shortness of breath.  I don't know that more rescue inhaler would help since my peak flow is normal.
