shoulder joint, the ball and socket articulation of the humerus with the scapula. The joint includes eight bursae and five ligaments, including the glenoidal labrum that deepens the articular cavity and protects the edges of articulating bones. It is the most mobile joint in the body. Also called humeral articulation.
It is common for young women to have irregular periods when they first begin to menstruate. This means that ovulation (when a womanâs body makes eggs) may not happen for a few months or even for a few years. So you may not have menstrual cramps when you first begin your period. After one, two, or three years, when your hormonal system is more mature, you might have more severe menstrual cramps.
Some pain, cramping, and discomfort during menstrual periods is normal. However, excessive pain that causes you to regularly miss work or school is not. The medical term for painful menstruation is dysmenorrhea. Primary dysmenorrhea occurs in women who experience pain just before and during menstruation, but who are otherwise healthy.
