👉 Myokinesis, also known as myoclonic spasm, is a type of muscular contraction that occurs when the muscles in your neck and shoulders are pulled together. When someone experiences this contraction, they may feel pain or discomfort in their neck and shoulder area. It's important to note that myokinesis can occur spontaneously or be caused by certain medical conditions such as spinal cord injury or nerve damage. If you're experiencing this type of contraction, it's important to seek medical attention immediately.
