Red Flags and the cervical spine

Red flags in patients with neck pain, headache, or dizziness are the main focus here, with special attention to cervical artery dysfunction and early stroke risk. Learners are taught how dangerous vascular problems can resemble common, non-serious symptoms such as fatigue, nausea, dizziness, or tinnitus, and why new, severe, spontaneous, and progressively worsening symptoms deserve particular concern. The summary stresses the importance of a thorough subjective assessment rather than relying on one test. Key priorities include reviewing cardiovascular risk factors, measuring blood pressure, and screening cranial nerve function before a full neck examination when suspicion exists. Both carotid and vertebral arteries are considered important, with discussion of how vascular pain can mimic musculoskeletal pain and how signs such as Horner syndrome may point to carotid involvement. A practical cranial nerve screening routine is also outlined, including visual field testing, nystagmus, facial movement, hearing, tongue deviation, swallowing, and shoulder strength. The overall message is to think systematically, document findings carefully, avoid full physical testing when cervical artery dysfunction is suspected, and refer urgently when warning signs are present.
