10Stiffness
People with shoulder impingement might feel stiffness around their shoulders or necks. This makes it harder to move or turn these parts around. Many people often describe it as a locking sensation. There can be many causes of a stiff shoulder, ranging from a neck sprain or whiplash to degenerative disc disease and other conditions associated with aging. If you do not feel better in a few days, make sure to seek medical attention to prevent further complications. [10]
