Welcome in H.C.M.
I have gone through your query and after analyzing and co-relating your symptoms with possible pathophysiological process it appears as you are suffering from chronic allergy
(raised eosinophil count
), possibly it had involved your nose and chest.
To confirm and for the treatment point of view you should do-
1- C.T.Scan paranasal sinuses
2- X-Ray chest.
3- Skin test for allergy.
By the inferences of above investigations and a thorough clinical examination will disclose the facts for making suitable diagnosis and that may be manage accordingly.
