About 9 months ago I got 10 units of botox injected to my forehead, which I had done 3 times in the past without any problems. However, I had not been to this doctor before. After this injection, I had drooping of my left eyelid for about 4 months. It was upsetting, but now my eyelid is back to normal and my forehead lines have returned. My question: since I had drooping before, how likely is it that I'll have drooping if I get a forehead injection again? I'm definitely not going back to the last doctor as I wasn't happy with him or his technique. But I am worried that the drooping will occur regardless. Any thoughts?
