### Patient: Doctor, I have been experiencing arm pain and headache along with diminished vision. I'm also having difficulty speaking and vomiting. Do you have any idea what might be causing these symptoms?
### Doctor: Based on your symptoms, it seems that you may be suffering from cerebral edema, which is an accumulation of fluid in the brain that can cause these various symptoms. We will need to perform some tests to confirm this diagnosis but I advise that we start treatment immediately to minimize further damage.
