<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, Ive been experiencing involuntary movements in my face and sometimes my arms. Its starting to become embarrassing around my friends, so I wanted to see if there was anything I can do about it.  <response>: It sounds like you may be experiencing tic disorder. In order to determine the best course of treatment, well need to do some testing. This will include psychotherapy, mental health counseling, and other diagnostic procedures such as an interview and evaluation. Well also need to do a Magnetic Resonance Imaging MRI and an Electroencephalogram EEG to get a closer look at whats happening in your brain. Additionally, well need to perform an ophthalmic examination and evaluation to rule out any other potential causes. We may need to use other diagnostic radiology and related techniques as well.
