Your arm is kept in your shoulder socket by your rotator cuff. The rotator cuff is a network of four muscles that come together as tendons to form a covering around the head of the humerus. The rotator cuff attaches the humerus to the shoulder blade and helps to lift and rotate your arm.otator cuff tears are more common in the dominant arm. If you have a degenerative tear in one shoulder, there is a greater risk for a rotator cuff tear in the opposite shoulder -- even if you have no pain in that shoulder.

The duration of the pain is usually between 10 and 30 minutes, although it might range from minutes to hours. The degree of pain can be mild or very severe. Growing pains are intermittent, with pain-free intervals from days to months.In some children the pain can occur daily.ecause these pains most often occur during years when the child's growth is not at its fastest rate, the pains are NOT associated with growing. The name was given in the 1930s to 1940s when the pains were thought to be from faster growth of the bones when compared to the growth of the tendons.
