Neck pain refers to discomfort or stiffness in the cervical spine, which connects the head to the shoulders. It can be caused by various factors, including poor posture, muscle strain, injury (such as whiplash), or underlying conditions like herniated discs, arthritis, or degenerative changes in the spine. Symptoms can range from mild soreness to sharp pain, and may radiate to the shoulders, arms, or upper back. Other symptoms include limited range of motion, headaches, or tingling sensations. Proper evaluation and treatment are essential to address the root cause and restore mobility and function.
