What causes a stiff neck?

There are several causes for a stiff neck, including:

1. Muscle strain or injury: Overuse of the neck muscles, such as from prolonged sitting or working in an awkward position, can cause muscle strain or injury. Sudden movements, such as whiplash, can also cause neck injuries.

2. Cervical spondylosis: This is a condition that occurs when the discs in the neck become worn or damaged, leading to the narrowing of the spinal canal and/or pressure on the nerves.

3. Herniated disc: A herniated disc occurs when the soft inner material of a spinal disc leaks out and presses on nearby nerves.

4. Rheumatoid arthritis: This autoimmune disease causes inflammation in the joints, including the neck joints.

5. Meningitis: This is a serious infection of the membranes surrounding the brain and spinal cord.

6. Osteoarthritis: This degenerative joint disease affects the cartilage that cushions the bones. It can occur in the neck joints, leading to stiffness and pain.

7. Fibromyalgia: This chronic condition causes widespread pain, including neck pain and stiffness.

8. Poor posture: Prolonged sitting or standing in an awkward position can put strain on the neck muscles and lead to stiffness.

9. Stress: Stress can cause tension in the neck muscles, leading to stiffness and pain.

10. Age: As we age, the normal wear and tear of everyday life can take a toll on the neck, leading to stiffness and pain.

If you are experiencing neck stiffness that persists for more than a few days, it is important to consult with a healthcare professional for proper diagnosis and treatment.
