Welcome in H.C.M.
I read your query regarding sinusitis
for quite long and now you feel much lethargic and at the same time your ears gets block from time to time.
No doubt your sinusitis is giving repeated infection to throat and thus obstructing the eustachian tube and leading to blockade of ear. I would like to suggest you to please consult your ENT doctor and get your sinus operated by FESS operation. By the expert hands results are excellent and you will be free from your symptoms.
Other way of treatment is by Grommet insertion on your ear drum.
I hope your query is answered.
