Thank you for sharing this. So sorry about the many medical problems. I too have had serious balance problems since my 11/13 Shingrix shot. It feels like I’m trying to walk on a boat in a storm. On 12/7 I “ saw” my Nurse Practioner via iPhone so no physical exam was done. Her best guess was crystals in the inner ear. AntiVert and vestibular exercises have not helped. My pharmacist said the balance problem must be completely unrelated to the Shingrix vaccine. But I wonder and am ambivalent about the second shot.
