### Patient: Doctor, I have been experiencing some strange symptoms lately. I have a disturbance of memory, fears and phobias, arm stiffness or tightness, and muscle pain. 
### Doctor: Based on those symptoms, it seems like you may have essential tremor. It is a neurological condition that causes involuntary shaking of certain parts of the body, typically the hands and head. It can also cause some of the other symptoms you mentioned.
