Rec'd botox on my forehead (20 units) & had minimal side effects after treatment (slight headache) which lasted a day. However, within a few days of receiving the botox I started getting dizzy every time I stood up from a squatting/prone position. Went to my PCP- blood pressure/bloodwork are normal. no change in medication, diet, etc. I have an appt w/ a cardiologist, but is it possible this is a side effect of the botox? I have never had this problem prior to the botox administration.
