Had Botox for the first time one month ago. 26 units on forehead and "11" lines. Every single time I rub my forehead my eyebrow muscles contract upwards. Which ever side I rub it contracts upwards. Lasts about 45 seconds. It's scaring me a lot. GP says "I'm fine". What is going on? I have appointment next wk with facial plastic surgeon. Is something bad happening to me?
