Hi
Thanks for writing to the forum!
I am sorry you are suffering so much. Maxillary sinusitis does cause cheek pain. Ethmoid sinusitis causes nose pain. Deviated nasal septum can be surgically corrected and will reduce your symptoms.Steam inhalation before bed time, raising the head end of bed, drinking plenty of hot fluids and doing deep breathing exercises too will help.
Hope this helps. It is difficult to comment beyond this at this stage. Do consult your ENT about surgery of DNS and surgical drainage of sinuses. Please let me know if there is any thing else and do keep me posted. Take care!
Have you tried a Nettie Pot?
