On November 30, 2021, I got the first Shingrix vaccination. A few days later, I noticed that the bathroom floor was giving under me (like the floor boards were not strong). Then over the next several weeks, I realized that I was having the same sensation in other rooms, even outdoors on concrete sometimes, and in parking garages. Floors that should have been totally stable were not. From the very beginning, I talked to others about it, including my doctors, but no one seemd to know what to think, except that it seemed to be some kind of vertigo.
I researched and found references to “rocking dizziness” and “mal de debarquement.” I found Dizziness and Balance.com (the Chicago Dizziness and Hearing Center. I was reassured by my understanding from them that this condition does eventually go away, although it may take a long time.
I went to the University of Washington Neurology Clinic, who had no idea what I had and referred me to the UW Otology Clinic, who eventually gave me four hours of exams, with the conclusion that they could not find labyrinthitis or anything else.
Over time, I notice the sensation less, but I do still notice it at times, especially under stress.
I have not gotten the second dose of Shingrix.
About a week ago, Googling “Shingrix vertigo” I discovered this chat line and the 2020 entry by @carolandersonl.
