There are many possible causes of left neck pain in patients, including the following. First, the patient may have thyroiditis, which leads to left neck pain. It is recommended that the patient seek anti-inflammatory treatment for related symptoms at a正规 hospital. Second, the pain could result from a localized suppurative infection causing left neck discomfort. Third, maintaining the same posture for prolonged periods, repeatedly performing the same movement, or using a pillow of inappropriate height during sleep may lead to neck pain on one side.
