From your complaints it appear that you may have some movement disorder
and affective lability. Both of these disorder can occur central nervous system
or nerve related disorders.
It is wise decision to seek neurologist
help. You may also need some imaging studies for confirmation of diagnosis.
If concurrent with this problem if you have anxiety, depressive symptoms, change in behavior, sleep and appetite problem, then you can visit psychiatrist
I hope this information has been both informative and helpful for you.
Wish you Good Health.
