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.
Painful menstrual periods are periods in which a woman has crampy lower abdominal pain, sharp or aching pain that comes and goes, or possibly back pain. Some pain during your period is normal, but a large amount of pain is not. The medical term for painful menstrual periods is dysmenorrhea. Many women have painful periods. Sometimes, the pain makes it hard to do normal household, job, or school-related activities for a few days during each menstrual cycle.
