I recommed getting botox in your hands or researching other treatment options to find something that works for you. You can also buy driclor in most Pharmacies, whilst it wasnt the best option for me it might work for you and saves you having to go to the doctor. Hope this helps x
My daughter is having the same issue but only while at school. I'm going to take her to her dr. next week and start there.
Hope she was given some help.
