### Patient: Hello doctor, I have been experiencing pain and swelling in my eye. It's been causing a lot of discomfort and I'm having trouble seeing properly.
### Doctor: Based on your symptoms, it's possible that you have orbital cellulitis. We need to perform some medical tests to confirm this. We'll start with a complete blood count (CBC), which will help us determine if you have an infection. We may need to begin intravenous fluid replacement and monitor your glucose level. We'll also need to perform an X-ray computed tomography (CT) scan of your head to determine the extent of the infection. Additionally, we will run kidney function tests and an electrolytes panel.
