What does it mean if I feel a lump under my jaw or on my neck, and what should I do about it?

Generally, if a lump is felt under the jaw or on the neck below the cheek, it may be caused by swollen lymph nodes, sebaceous cysts, mumps, etc., and targeted treatment is required. Specific analyses are as follows:

1. Swollen Lymph Nodes

Swollen lymph nodes usually result from inflammation in the oral cavity or pharynx, where inflammatory factors affect areas such as the jaw and neck, leading to lymphadenitis. This condition manifests as enlarged lymph nodes, causing the aforementioned lump. Under medical guidance, medications such as amoxicillin capsules or cefaclor capsules can be taken to alleviate symptoms.

2. Sebaceous Cyst

A sebaceous cyst may develop due to inadequate local hygiene, resulting in blocked sebaceous gland openings and impaired secretion of sebum, thus forming a lump. Treatment typically involves surgical removal of the cyst at a hospital.

3. Mumps

Mumps is usually a respiratory infectious disease caused by the mumps virus, often occurring when the body's immunity is low. Under stimulation by inflammatory factors, swelling in the parotid (salivary) gland area commonly occurs, with a palpable hard mass. It may also be accompanied by pain, leading to the sensation of a lump under the cheek or on the neck. Under medical supervision, antiviral and anti-inflammatory drugs such as ribavirin tablets or dexamethasone acetate tablets can be used for treatment.

In addition to the above conditions, folliculitis, pharyngitis, tonsillitis, and other diseases may also cause this phenomenon. It is advisable to get adequate rest, maintain a regular lifestyle, avoid excessive fatigue, and balance work with rest.
