What is the reason why you are not able to turn your head one way?

Inability to turn your head in one direction could be due to muscle strain, injury, or stiffness in the neck, often caused by poor posture, sleeping awkwardly, or overuse. It might also result from conditions such as cervical spondylosis or a pinched nerve. If the limitation persists or is accompanied by pain, it’s advisable to seek medical attention for an accurate diagnosis and appropriate treatment.
