What causes pain on the right side of the neck, and how is it treated?

Under normal circumstances, pain on the right side of the neck may be caused by poor posture, overexertion, cervical disc herniation, cervical lymphadenitis, or carotid artery stenosis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Poor Posture

Prolonged poor posture, such as looking down at a mobile phone or working at a computer, may lead to neck muscle tension, causing pain on the right side of the neck along with discomfort in the shoulders and upper back. Improving sitting and standing posture, taking regular breaks, and performing neck stretching exercises in daily life can help alleviate symptoms.

2. Overexertion

Excessive muscle use may result in microscopic muscle fiber damage, leading to pain, swelling, and limited movement on the right side of the neck. Applying heat therapy can improve blood circulation and relieve muscle tension, while cold therapy may help reduce inflammation.

3. Cervical Lymphadenitis

Lymph nodes are part of the body's immune system. When the body experiences an infection, cervical lymphadenitis may develop, causing lymph node enlargement and pain, which in turn leads to pain on the right side of the neck, fever, and general malaise. Treatment may include medications such as penicillin V potassium tablets, cefixime capsules, or roxithromycin dispersible tablets, taken as directed by a physician.

4. Cervical Disc Herniation

Degenerative changes in the cervical discs or trauma may lead to cervical disc herniation, compressing nerve roots and resulting in pain on the right side of the neck, as well as numbness and weakness in the upper limbs. Under medical supervision, medications such as ibuprofen tablets, acetaminophen tablets, or diclofenac sodium sustained-release capsules may be used for treatment.

5. Carotid Artery Stenosis

External trauma to the neck may cause carotid artery stenosis, impairing blood supply and leading to pain on the right side of the neck, often accompanied by symptoms such as blurred vision and facial numbness. It is recommended to visit a qualified hospital where procedures such as carotid endarterectomy or carotid artery stenting may be performed under a doctor’s care.

In daily life, it is important to get adequate rest and avoid maintaining the same posture for prolonged periods. If significant discomfort occurs, prompt medical evaluation and treatment are advised.
