You will need to check with your doctor to know for sure the cause of getting this terrible taste and smell off and on for about 2 years. The odds are against this being due to a brain tumor. However brain tumors can result in a variety of odors. Acid reflux and sinusitis are the 2 most likely causes of your problem. Another possible cause is atrophic rhinitis. Over the years this condition has decreased, so it is less likely to be the cause of your problem.
Gastroesophageal reflux disease (GERD) is the back flow of stomach contents, including digestive juices, into the esophagus or food tube. This is most commonly called acid reflux or heartburn. This reflux can come all the way up into the mouth and nose. When this happens the material can be aspirated, dribbling into the windpipe and lungs. This could explain your symptoms.
GERD can cause the following symptoms:
pLEASE HELP!! THANK YOU FOR YOUR TIME! I wake up and go to sleep feeling congested. I have gone to the doctor and he prescribed flonase/rhinocort and steroids. Nothing helped and caused a lot of nose bleeds. Recently I noticed that when I yawn I smell pus and feel pain on the xyphoid process when I bend down. (I have no history of heart problems) I dont have any fevers indicating infection.
Do you think that the congestion is causing the ache on the area just mention?
Does nose congestion cause respiratory problems?
Do you think that if there is drainage infection, it is capable of traveling thru the respiratory system?
thank you
