My dermatologist said that dizziness is not a side effect of botox. Having researched I found that not to be true. Since I had the injection 6 weeks ago, I have been dizzy. I went to my GP 2X, an ENT 1X and was sent for an MRI of my brain and ears. I have not had a stroke, hemmorage and no tumors were found. Each and every doctor I've seen said this was not caused by the botox, but it began 3 hours after the injections. I want my life back and need to know if anyone else has had this side effect and how long this will last.
