### Patient: Doctor, I have been experiencing a bad headache and noticed some muscle stiffness and tightness in my body, specifically in my arms. I'm not sure what's going on but it's been bothering me for a while now.
### Doctor: Based on your symptoms, it sounds like you are experiencing cerebral edema which is a swelling of the brain caused by excess fluid accumulation. It can cause the symptoms you described such as headaches and muscle stiffness. We need to take immediate action to treat this condition.
