### Patient: Hi doctor, I've been experiencing swelling and pain in my salivary gland. What do you think is wrong and what tests do I need?
### Doctor: Based on your symptoms, it sounds like you may have sialoadenitis. In order to confirm this, we'll need to perform a few medical tests. The first one is an X-ray computed tomography (Scan ct) to get a detailed image of the affected area. We'll also need to do an intravenous fluid replacement to help reduce the inflammation. Additionally, we may need to do a CAT scan of your head (Head ct) to see if there are any other issues contributing to your symptoms. Finally, a blood culture will be necessary to check if an infection is causing the sialoadenitis.
