Throat and chest problems.

I have been suffering from sinus for few years and my tonsils size are very large also. Mucus is coming very frequent in my throat and have to be blow out from mouth. Moreover there is some nasal deviation in my right side of nose due to which breathing is sometimes troublesome for me. Also i got frequent itching in tonsils, lower down to throat and regular cough with breathlessness which usually last for hours if not taken any antiallergic. Also many times itching in lower middle portion of neck  while inhaling occurs. While after excess coughing something goes up and down with" sound of kharr kharr" in chest while exhaling.Also, chest tightness and shortness of breath felt. Last month I got checked. My chest x ray blood reports and PFT test were ok.  Also nasal x rays shows deviation and sinusitis which i described . But IGE serum level was above 700. Nowadays i am feeling very frequent cough and itching with cough and breathlessness .
