I have sinusitis and clogged ears after drinking ginger tea. it has been 2 weeks and my symptoms are still here. what could this be?

Food intolerance: Your symptoms could be due to an intolerance of any of the ingredients found in the tea you are drinking. If you eat a lot of sugar this could also be a fungal sinusitis. Cut out all sugar and dairy products. Take a high potency Probiotic twice a day and drink a lot of water. Performing sinus rinses with a netti pot twice a day can greatly relieve sinus congestion.
