What causes pain under the chin when pressing?

Generally, pain when pressing under the chin may be caused by improper sleeping posture, muscle tension, submandibular sialadenitis, folliculitis, or lymphadenitis. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:

1. Improper Sleeping Posture

Maintaining an incorrect sleeping position for a prolonged period—such as placing pressure on the chin—may impair local blood circulation, leading to tenderness upon palpation of the jaw area. This may be accompanied by local numbness or soreness. It is advisable to adjust sleeping posture and avoid prolonged pressure on the chin.

2. Muscle Tension

Remaining in the same position for extended periods, especially with forward head posture, can cause excessive tension in the jaw muscles, resulting in tenderness upon pressure. This may be accompanied by neck stiffness and headaches. It is recommended to regularly stretch neck muscles, maintain proper sitting posture, and avoid prolonged head-down positions.

3. Submandibular Sialadenitis

Submandibular sialadenitis is an inflammation of the submandibular gland caused by bacterial infection, which may lead to jaw pain and swelling, causing tenderness upon palpation. It is often accompanied by symptoms such as fever, local redness, swelling, heat, and pain. Treatment should be conducted under medical guidance using medications such as moxifloxacin hydrochloride tablets, amikacin sulfate injection, or cefixime tablets.

4. Folliculitis

The submandibular area is rich in sebaceous glands. When pores become blocked and secretions cannot drain properly, folliculitis may develop. This typically presents as tenderness upon pressing the jaw, along with pustules and redness and swelling. Treatment should follow medical advice and may include topical medications such as fusidic acid cream, mupirocin ointment, or oral cefuroxime axetil tablets.

5. Lymphadenitis

Lymph nodes are part of the immune system. When submandibular lymph nodes are infected by pathogens such as bacteria or viruses, lymphadenitis may occur. Swollen lymph nodes can cause tenderness upon pressing the jaw area and are often accompanied by systemic symptoms such as fever and fatigue. Under medical guidance, treatment may include medications such as amoxicillin capsules, clarithromycin capsules, or metronidazole tablets.

In daily life, appropriate physical exercise can be increased to enhance physical strength and boost the body's immunity.
