<s>[INST] I have had a cold with severe congestion for over a week. The congestion worsened so that it felt like my ears were plugged. My sinuses were also very congested. I experienced severe dizziness and vomiting, had to go to the Emergency Room. They wondered if I was suffering from allergies. I do have seasonal allergies but have never experienced this degree of dizziness before. Could it just be fluid buildup in the inner ear causing my dizziness? They prescribed medication for nausea, valium and meclizine for the vertigo, prednisone for inflammation and a nasal spray for nasal congestion. Also recommended I use Theraflu to further loosen the congestion. What are your thoughts or ideas? [/INST] I agree that this could very well be due to a problem with your eustachian tubes in your ears caused by allergies.  Seasonal allergies can cause fluid build up in the ear which can lead to sensations of dizziness.  I agree with the medicines that have been given to you by the ED.  If you are still having trouble, a medicine like sudafed might help in drying out your ears. </s>
