This occurs when the rotator cuff tendons become compressed or irritated as they pass through the narrow space (subacromial space) between the shoulder blade and the top of the shoulder joint, resulting in pain and limited movement, especially when raising the arm.

This condition involves stiffness and pain in the shoulder joint, often due to inflammation and thickening of the shoulder capsule, leading to restricted mobility and pain with movement.

When the upper arm bone (humerus) pops out of the shoulder socket, it can cause intense pain, swelling, and instability in the shoulder joint.

Like other joints, the shoulder can develop arthritis, leading to pain, stiffness, and reduced range of motion, particularly in activities that require overhead movement.

The labrum is a ring of cartilage that helps stabilize the shoulder joint, and tears in this structure can cause pain, clicking or catching sensations, and feelings of instability in the shoulder.

Cervicogenic headaches are a type of headache that originates from issues in the cervical spine (neck). They can sometimes act similar to a tension-type headache or migraine. These headaches arise from abnormalities or dysfunction in the cervical spine, such as misaligned vertebrae, muscle tension, or irritated nerves. Symptoms: Cervicogenic headaches typically cause pain on one side of the head, often starting in the neck and radiating to the back of the head, temples, forehead, or behind the eyes. The pain is usually dull or aching and may be accompanied by neck stiffness or limited range of motion.

Inflammation of the tendons in the shoulder, such as the biceps tendon or the tendons of the rotator cuff muscles, can cause pain, especially with overhead activities.
