No one likes going thru the vertigo episodes for sure! When mine come on it can last for a day or two or weeks. From the beginning of this Pandemic my fear was the physical aspect of diminished respiratory issues. My past health history includes Pneumonia with 4 weeks of antibiotics and unexplained Pulmonary Embolisms which I am still taking blood thinners for. I know what those 2 issues felt like and I can't imagine having anything worse.
Think of the benefits vs the possible negative. I hope you find the benefits worth it. PLAN your vaccine for days when you have no obligations other than to stay home and rest. My first shot was a piece of cake, my 2nd shot I had some body aches the following day and took Ibuprofen and stayed home all day. I woke up feeling fine after that.
From what I am reading the vaccine causes an immune response and in some people can cause inflammation in the inner ear which brings on vertigo. Have heard this about both Moderna and Pfizer.
