Muscles in the Human Body. Muscles are how we move and live. All movement in the body is controlled by muscles. Some muscles work without us thinking, like our heart beating, while other muscles are controlled by our thoughts and allow us to do stuff and move around.
Cramping and Breast Tenderness. Cramping is one of the most common symptoms a woman experiences before, during or after her menstrual cycle. Caffeine contributes to cramps because of its diuretic nature--it increases urine production and promotes dehydration. In addition, coffee contains oils that may inflame your intestines and cause cramping.
Menstrual cramps (dysmenorrhea) are throbbing or cramping pains in the lower abdomen. Many women experience menstrual cramps just before and during their menstrual periods. For some women, the discomfort is merely annoying. For others, menstrual cramps can be severe enough to interfere with everyday activities for a few days every month.
