Started PR today...not too bad. Hoping to get some benefit from it. Dr is also having me get the Alpha 1 test done. Unlikely I have it, but he believes I've had COPD many years (late 20s, early 30s). He also wants me to take Prednisone for the chest tightness I've been having, Saud could be from my sinus allergies. He said just in case.
