I had botox done a few years ago and 3 days after I got it I felt like I had very bad hangover. A few years later I tried it again convincing myself it was a coincidence but I got even sicker the second time again 3 days after the injection. My symptoms are dizziness, pressure in my head, nausea. The symptoms only last 1 day but are scary enough I am afraid to try again. I loved the results otherwise. Can anyone tell me why this happens? Is it an allergy?
