Thanks for query to H.C.M. Forum.
I think ,you must have operated for SINUSITIS
Now there are ,
pain or pressure around eyes,
green mucus,itching in the ear,
breathing from mouth.
In my opinion , this is not related to sinus surgery
,rather allergic bronchitis
All above mentioned symptoms are due to allergy.
Now take antihistamine with potent bronchodilator
after the consultation of another E N T specialist/ physician.
Hope I have answered your question.
If further any question I will help.
Get well soon.
