Hi, From your complaints it appears 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 too. I hope this information has been both informative and helpful for you. Wish you Good Health.
