Hot pain in the neck may be caused by the following reasons: 1. Severe soft tissue injury to the neck, often caused by a direct violent blow to the neck, such as an impact in a car accident, may quickly lead to subcutaneous bleeding and sterile inflammation within the soft tissue, resulting in hot pain. 2. The fracture of the cervical spine is often caused by a passive violent injury such as pulling or twisting of the neck, and the severe pain caused by the fracture may cause the above-mentioned sensation. 3, caused by nerve stimulation of the cervical spine, for example, when neurogenic cervical spondylosis occurs, the above-mentioned sensation is caused by the stimulation of the nerve roots. 4, caused by some skin lesions of the neck. For example, when contact dermatitis or skin allergy occurs, the lesion on the skin surface causes the patient to have similar sensations.
