My twitching started 13 months ago. Prior to my twitches I had a neck problem for two months. There is a loss of cervical lordosis in my neck, which means the shape of the cervical spine changed from c shape to reverse c, which was triggered by a muscle spasm in my neck. My neck problem started just three days after I ...received a seasonal flu shot. So I dont know if the flu shot is the root of all these problems. Or twitches are a result of the problem in my neck or because of pain medication/muscle relaxant medicines might have triggered these twitches. I really dont know
