Persistent cough and breathlessness.

From month of MAY I get persistent feeling of cough and at times I do spit out clear liquid kind of cough, major issue is from MAY coz I struggle to breathe, and mostly after food in the evening I feel feverish from last 1 month I went to a plumonologist he asked me to get blood test of Total IGE and absolute eosinophil count to which my IgE was 528 and Absolute count was 600 Which he said its kinda normal.. he gave me meds named Torkast FX and Spiodin AX for 15days which I ate but he comes to my town (jamshedpur) twice a week, I had those meds for 15 days My question is.. for this issue should I continue treatment from him or visit any ENT specialist Nd why i get cough, breathlessness and consistent cough what can be the reason behind. On my next visit he told he will get my PFT done. Plz suggest something.
