Lungs Problem. Coughing since 2months?

After suffering from coughing for 2-3 months I visited pulmonologist 3 months back and I was suggested for Blood IgE,  PFT and FENO test. I have attached the Reports. For IgE I was given allergy tablets and I have completed d course. I was also given Esiflo 500 transcaps to take with Lupihaler 2 tablets /day (9am and 9pm). But I took 1 tab per day and stopped dat medicine after 2 days as I felt head spinning whenever I took dis. Now again I have started dis medicine 1 tab per day though I feel some uncomfortness. Now should I continue dis medicine Esiflo with one tab/day ? How long should I take dis ? My doctor is not contactable now so want to know according my PFT and FENO report how bad is my lungs ? After Angiography on 1st Jan'20 , I became Vegetarian, Non Smoker Non Alcoholic. Walk for 2 hrs/day. Please reply in details on - 1) Esiflo 2) according to PFT and FENO how bad is my lungs as sometimes I feel short of breath and chest heaviness -No regular coughing since 2months?
