Hi, I've been a migraine sufferer for 30 years but but could go for months in between. They lasted 3-4 days. I had my first astrazeneca vaccine in February this year and I started getting more frequent migraines along with dizziness. I got my second vaccine in May and the migraines and dizziness continued. I got my eyes examined a couple of months ago and was prescribed stronger lenses, my eyes, I was told, were healthy. Since then my migraines have been worse, I'm getting them almost every week with dizziness. I'm sure the vaccines have played a part in this but I don't know whether the eye test actually made them worse too along with the stronger lenses. My doctors don't acknowledge any connection with the vaccines, they seem to know very little about them. Can it take this long to get used to new lenses? Thank you.
