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 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.
If a woman has endometriosis, cells that resemble the lining of the uterus exist on other places within her pelvis, such as on her bladder, bowel, or vaginal walls. These cells can be triggered with a period and cause more pain and inflammation, which is why women with endometriosis tend to have more severe period pain. Sometimes the uterus isnât aligned neutrally within the pelvis, and this can contribute to pain that may be one-sided or to pain in the lower abdomen.
