When considering whether to undergo a CT scan for a swollen left jaw, there are several factors to take into account, including the nature of the swelling, associated symptoms, and the potential benefits and risks of the scan itself.

First, it’s important to understand what might be causing the swelling in your left jaw. Swelling in this area can be due to a variety of reasons, including but not limited to infections (such as a dental abscess), lymphadenopathy (swollen lymph nodes), salivary gland issues (like sialadenitis or stones), or even tumors. The fact that you can feel a soft, movable mass suggests that it could be a swollen lymph node or a salivary gland issue, but it’s essential to have a proper evaluation to determine the exact cause.

In terms of whether a CT scan is necessary, it is generally recommended to seek medical evaluation sooner rather than later, especially since you have noticed a change in your body. While it may not be urgent to have a CT scan immediately, it would be wise to consult with a healthcare provider who can perform a physical examination and assess your symptoms in detail. They may recommend imaging studies based on their findings.
A CT scan can provide detailed images of the structures in your jaw and neck, which can help identify any abnormalities such as tumors, infections, or other issues that may not be visible through a physical examination alone. However, it’s also important to consider the risks associated with CT scans, primarily the exposure to ionizing radiation. While the radiation dose from a single CT scan is relatively low, it is still a factor to consider, especially if there are alternative imaging modalities available, such as ultrasound or MRI, which do not involve radiation.

If you are concerned about potential underlying conditions, such as HIV, it’s crucial to address those fears with your healthcare provider. They can provide appropriate testing and counseling, which may alleviate some of your concerns and help you focus on the current issue with your jaw.

Regarding your question about waiting for pain to develop before seeking medical attention, it is generally not advisable to wait for pain to become a factor. Swelling can indicate an underlying issue that may worsen over time, and early intervention can often lead to better outcomes. If the swelling is persistent, changing, or accompanied by other symptoms (such as fever, difficulty swallowing, or significant changes in your overall health), it is best to seek medical advice promptly.

In summary, while a CT scan can be a useful diagnostic tool, the decision to proceed with one should be based on a thorough evaluation by a healthcare professional. They will consider your symptoms, medical history, and any potential risks associated with imaging. It is always better to err on the side of caution and seek medical advice sooner rather than later, especially when it comes to unexplained changes in your body.
