I had a similar problem snorting mucus all the time. Mine was mainly in the nasal area. Went to various ENT specialists with no result. Eventually had a camera put down my stomach and they found I had a hiatus hernia. Gases from my stomach were able to leak into my throat area. I have recently been prescribed Omniprazole to reduce stomach gases leaking into this area. Now much improved after 10 years.
If you have no luck with the above then I would consider a camera down your stomach (before surgery) to see if there is a problem there. Test only takes 2 mins.
Hi, when there is excessive mucous, it can cause cough and consequent vomiting. Sinus infections cause a post nasal drip where secretions from the nose go backward into the throat and irritate causing cough. Cough is a protective mechanism by the body as it helps to prevent infections.
The best way to get to the bottom of your sinus issues is to see an ENT. A good examination inside the nose with a camera might give the ENT more information as well as a CT scan of the sinuses. If it is a chronic sinus infection, 4-6 weeks of antibiotics are pretty standard in addition to nasal steroid sprays, oral steroids, and salt water irrigations of the sinuses. If this fails to solve the problem, sinus surgery is usually recommended. Regards.
