Why does my shoulder hurt when I yawn?

Yawning involves stretching the muscles in the mouth, throat, and ears, but it doesn't typically cause shoulder pain. If you associate your shoulder pain with yawning, it's important to consider any underlying conditions or activities that may be the actual source of the discomfort. Here are a few possible causes of shoulder pain unrelated to yawning:

Rotator Cuff Injury: The rotator cuff is a group of muscles and tendons that help stabilize the shoulder joint. If the rotator cuff is injured, it can cause pain in the shoulder, especially during certain movements.

Stiffness or Muscle Tension: Prolonged sitting, poor posture, repetitive arm movements, or certain sports activities can lead to stiffness or muscle tension in the shoulder area, which may be aggravated during yawning.

Arthritis: Conditions such as osteoarthritis or rheumatoid arthritis can affect the joints, including the shoulder. Pain, stiffness, and decreased range of motion are common symptoms of arthritis.

Muscle Strain or Tear: Overuse or sudden strain during physical activity can result in a muscle strain or tear, which can lead to pain and tenderness in the affected area.

Nerve Impingement: A nerve that supplies the shoulder may be pinched or irritated, causing pain that may be experienced in the shoulder region.

Previous Shoulder Injury: If you've had a shoulder injury in the past, it may be more susceptible to pain and discomfort, even with seemingly unrelated activities like yawning.

It's important to note that shoulder pain should not be directly attributed to yawning. Consult a healthcare professional to accurately identify the source of your pain and receive appropriate treatment or advice for managing the discomfort.
