Hi. Thanks for your query. Read and understood your history of sinus infection, blowing the nose and getting a vertigo, nausea, vomiting and pooping sound. This indicates that the nasal discharge/ air entered through the dysfunctional Eustachian tune into the middle ear increasing sudden pressure and causing the symptoms that you have. I would advise you the following: - Stop blowing the nose. - Get a consultation of an ENT and get examined and to get the following medicines: Antibiotics, strong anti-inflammatory and steroids amlong with oral and nasal decongestants. This may heal up the things faster. Get a bed rest and steam inhalation. Avoid the temperature changes. This should help you, have a regular review with your ENT to get adjusted withe the medicines and its dosages. Symptomatic treatment for vertigo in the form of medicines if required.
