Intermittent Swelling of the Salivary Gland: Causes and Concerns - Otolaryngology

Intermittent swelling of the salivary glands can be concerning, especially when it occurs without pain, redness, or other accompanying symptoms. Given your description, it seems that the swelling is transient and resolves on its own within a couple of hours, which is somewhat reassuring. However, it is important to consider various potential causes for this phenomenon.

One common cause of intermittent swelling in the salivary glands, particularly the parotid gland (the largest salivary gland located near the jaw), is the accumulation of saliva due to blockage or narrowing of the salivary ducts. This can occur due to dehydration, which can lead to thickened saliva, or the presence of salivary stones (sialolithiasis). When the duct is blocked, saliva can build up, causing temporary swelling. This is often not painful and can resolve when the blockage is cleared, either spontaneously or through actions like chewing or sucking on sour candies, which stimulate saliva production.

Another possibility is a condition known as parotitis, which is inflammation of the parotid gland. This can be viral (such as mumps) or bacterial in nature. However, since you mentioned that there is no pain or redness, this is less likely.
Stress and fatigue can also contribute to muscle tension in the jaw and face, which might create a sensation of tightness or swelling. If you are experiencing significant stress due to your busy work schedule and lack of sleep, this could manifest as muscle tension, leading to the feeling of swelling in the cheek area.
While the symptoms you describe do not immediately suggest a serious condition such as cancer, it is essential to rule out any underlying issues. Salivary gland tumors, although rare, can present with swelling. These tumors can be benign or malignant, and they may not always cause pain or other symptoms initially.
Given your concerns about cancer or tumors, it is advisable to consult with a healthcare professional. A thorough examination, including imaging studies such as an ultrasound or MRI, may be warranted to assess the salivary glands and rule out any abnormalities. Additionally, a healthcare provider may consider blood tests or a biopsy if there are any suspicious findings.

In summary, while your symptoms may be related to benign causes such as salivary duct obstruction or muscle tension, it is crucial to seek medical advice to ensure that more serious conditions are not overlooked. Maintaining good hydration, managing stress, and ensuring adequate sleep can also contribute positively to your overall health and may alleviate some of the symptoms you are experiencing.
