Welcome in H.C.M.
I have gone through your query regarding tiredness
, heavy head, headache, eye pain
, high ear pressure all these are in favor of sinusitis
. As you said about radio logical findings like mucosal thickening in different sinuses along with septal deviation, all these indicates local nasal and paranasal sinus pathology and needs correction.
Ideally you should consult your ENT doctor for -
2- FESS operation to make patent osteomeatal complex.
Both above are surgical interventions but will be beneficial for you.
