Thanks for writing in to Healthcare Magic!
You are right, you are having the dystonic spasms due to side effects of Ganaton
You should stop it flush but I would suggest you to consult your physician rather than managing the matter all by yourself. He should know that you had this problem so to remain alert in future.
is a complex disease to be handled by you rather it is a challenging disease for even the specialists.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
