Thanks for consulting H.C.M. regarding your medical problems.
I have gone through your query and it appears very un pleasant that that even after surgery you have headache, itching, sensation, heaviness in eyes .
here I would like to tell you that all these features are indicative of sinusitis, some times this sinusitis is allergic, in allergic sinusitis
usually surgery does not help and better to treat such cases conservatively.
In your case I would like to tell you that if your symptoms are seasonal than take conservative treatment , but if it remains through out year than you should proceed for treatment of chronic allergy
1- Use topical steroidal nasal spray
2- Sub mucous Hydro cortisone injection
over inferior turbinate.
3- Coblation assisted turbinate reduction.
I hope these modalities of treatment will help you.
