Thanks for choosing health care magic for posting your query.
From the description that you have given, it appears that you are having a sever bout of sinusitis
. Coming to your question proper first, Duolin
repsules inhalation with steam may not help you with sinusitis. The first thing you should do is start plain steam inhalation and do it repeatedly. Also start a decongestants such as Allerid D which is mostly available OTC. If the symptom persists then you should consider taking antibiotics and also consult an ENT surgeon who can consider you for FESS surgery if the symptoms are severe.
Hope I am able to solve your concerns.
If you need any further help in detail, I will be more than happy to help you.
Wish you good health.
