Pain behind the ear extending to the neck, with pain upon turning the head.

Generally, pain behind the ear extending to the neck, especially when turning the head, may be caused by factors such as muscle strain, lymphadenitis, or sternocleidomastoid tendinitis. Treatment options include physical therapy and medication. Specific analyses are as follows:

1. Muscle Strain

Improper exercise posture or excessive physical activity can lead to over-contraction of muscles or stretching beyond their capacity, resulting in muscle strain. Symptoms include muscle pain and restricted movement. Physical treatments such as cold compresses with ice packs and compression bandaging may help.

2. Lymphadenitis

Bacterial invasion through the skin or mucous membranes can cause infection, leading to inflammatory reactions in the regional draining lymph nodes. Main symptoms include swollen and painful lymph nodes. Under medical guidance, treatment may involve oral medications such as cefaclor capsules or roxithromycin capsules.

3. Sternocleidomastoid Tendinitis

Sudden excessive head rotation or poor sleeping posture may cause acute injury and inflammation of the sternocleidomastoid muscle. Clinically, this mainly presents as neck pain and limited neck movement. Under medical supervision, medications such as ibuprofen sustained-release tablets or Zhongtongan capsules may be taken to relieve pain.

In addition to the above common causes, the condition may also be associated with diseases such as cervical tuberculosis, cervical spondylosis, or lymphoma. If symptoms persist, patients are advised to promptly visit a hospital for relevant examinations to identify the underlying cause and receive appropriate, targeted treatment under medical guidance.
