I am frustrated with my asthma. I am 26 years old and developed asthma two years ago. It went untreated for almost a year, then I started taking Qvar (two puffs twice a day) and moved to Symbicort. I am currently on 180/4.5 of Symbicort, two puffs twice a day. While it helped a lot, I still have near-constant chest tightness. I was worried that it might have damaged my lungs or had done remodeling, but I underwent HRCT, which found no abnormalities. My PFT results are as follows: Pre-bronchodilator FVC: 6.18 L (116 % predicted), FEV1: 4.53 L (102 % predicted), FEF25: 75 3.45 L (75 % predicted), Ratio: 73 % (88 % predicted), RAW: 2.27 (134 % predicted), sGAW: 0.10 (38 % predicted), Post-bronchodilator FVC: 6.34 L (119 % predicted) change is of 3 %, FEV1: 4.69 L (106 % predicted) change is of 4 %, FEF25-75: 3.79 L (83 % predicted) change is of 10 %, Ratio: 74 % (89 % predicted) change is of 1 %.
I was diagnosed with mild persistent asthma. My question is, how can I have pretty much normal spirometry with normal HRCT but still have these daily annoying symptoms. Is it possible this tightness is my new normal? I am desperately trying to get back to how I was before I developed asthma. I would appreciate any suggestions. I am thinking of Montelukast and asking to switch to Trelegy. The cardiac workup was normal (Echo and ECG).
