Alicia, I only realized my problem once my sister had her first (and last) injection in 2005, for her it happened the very same day, 2 weeks before she saw her eye doctor and he told her she has the vision of an eagle, and after her Botox shot, her vision became blurred when she got out of the office and when she went to bed that night, her neck was in pain. My shoulders & neck pain took at least 3 years to dissapear after my last injection because I had have few Reiki treatments and the pain was gone few days after Reiki treatment. As for my vision, nothing changes, I still need glasses to read.
