Hi Sylvia,
I'm sorry that you are still having problems. It takes varying amounts of time for botox to wear off. Most doctors won't give botox more often than every 8 weeks so I am a bit surprised that you were getting it every month over a course of months.
You could also be suffering from a Bell's Palsy type thing on that side of your face. If you stopped the shots in June, we are still in that month, so it hasn't been very long. It could still be months before the botox wears off. It should eventually wear off, though. I think that time will be your only answer for your question. You might want to get a 2nd opinion from another neurologist that specializes in movement disorders who is very familiar with Hemifacial Spasm. I recommend it.Sorry that I couldn't help more. I wish you luck and hope that things improve for you.
Shirley in AR.
