I have also suffered from these muscles spasms and tics since the auto accident I was in that caused the concussion. I did not have them before I sustained the concussion.

It can be a symptom of neuroendocrine dysfunction which can be caused by concussion.

Since I have been placed on replacement hormones in the last several weeks, the tics and random spasms have reduced. It can take a year for the hormone to become balanced in my body, so I'm giving it that long to disappear, although I'm hoping it takes less time.

An endocrinologist experienced with treating hormone imbalance caused by concussion can treat neuroendocrine dysfunction. Unfortunately, they are few and far between...
