Cervical pain refers to any discomfort or pain in the neck region, which is the upper part of the spine. The most common causes of cervical pain include:

1. Poor posture: Sitting or standing in the same position for a prolonged period can lead to muscle strain, which can cause cervical pain.
2. Muscle strain or injury: Strain or injury to the muscles and ligaments that support the neck can cause cervical pain.
3. Degenerative disc disease: This condition occurs when the spinal discs in the neck wear out and cause pain.
4. Herniated disc: A herniated disc occurs when the cushion between the spinal vertebrae in the neck ruptures or bulges out, which can put pressure on the nerves and cause pain.
5. Osteoarthritis: This is a type of arthritis that affects the joints in the neck, causing pain and stiffness.
6. Pinched nerve: When a nerve in the neck is compressed or pinched, it can cause cervical pain.
7. Infections or tumors: In rare cases, infections or tumors can cause cervical pain.
