Dysmenorrhoea is described simply as a pain during menstruation. It is a very common symptom, which is experienced by 45-95 % of females of reproductive age.
Menstrual cramps appear like throbbing, cramping, or dull pains in the lower part of the abdomen. The pain can go to your thighs and the lower back too. Some women with dysmenorrhoea experience loose stools, nausea and vomiting, dizziness, and increased sweating.
Menstrual cramps usually begin at the onset of or just before the menstruation and last about eight hours to three days every month. For some females, it is only an irritable feeling. However, some women experience a severe pain, which affects their daily routines for several days each month.
