i have very dry sinuses, throat, mouth, lips, and lungs. this causes my sinuses to get infected almost every other month and lasts for 2 to 3 weeks. it also cases a secondary lung infection every time. this has been going on for a little over a year, since i quit chewing tobacco. i noticed that i was becoming dry so i decided to quit. then the dryness got even worse and then i quit smoking pot and the dryness got even worse. my doctor just prescribes sybicort and nosonex. they don't work but i take them so he cant say that I'm not following through with the treatment. we did allergy tests and I'm not to anything. all immune deficiency and hormone tests are good "normal".the cat scans of my sinus and lungs find a minor sinus disease. he says just to keep doing the medication. i do have some saliva and mucus but it is very thin and does not provide protection from the above body parts from getting very irritated. someone please help! i am so desperate. i wake up with dread every day that i am still alive and have to live with this. also i don't smoke anything now and have not smoked cigarettes for 10 years and only did for about 4 years.
