A coworkers daughter has excessive sweating in her armpits and has been getting botox injections for a few years now. From my coworker, I've heard that the injections are extremely painful; so much so that the doctor commented that it's rare that he sees patients for more than one treatment. That being said, it has worked like a charm. She has no excessive sweating in her armpits. For her, it was worth the pain.
