The clinical course was reported as follows: When I received the first vaccine, I felt a bit dizzy and a week later, intense dizzy spells began taking place, especially after eating. My ears felt clogged, I became sensitive to sound, and thought I was allergic to food. Went to an allergist and discovered allergies, inflamed Eustachian tubes, and fluid in the ear. Allergist recommended a neurologist based on my described symptoms. After second vaccine, dizzy spells have continued almost daily, coinciding with confusion, forgetting words/brain fog, tingling in face/lips, and shortness of breath. Not sure if this is from the vaccine, but these symptoms began a week after my first vaccine and have continued after the second. I am following up with my doctor to ensure it is nothing else, I just wanted to bring it to awareness just in case and for study purposes.
