AB  - Primary  dysmenorrhea  is  menstrual  pain  associated  with  menstrual  cycles  in  the  absence  of  pathologic  findings.  Pain  usually  begins  within  1–2  years  after  the  menarche  and  may  become  progressively  more  severe.  The  frequency  of  cases  increases  up  to  age  20  and  then  decreases  with  both  increasing  age  and  parity.  Fifty  to  75%  of  women  are  affected  by  dysmenorrhea  at  some  time  and  5–6%  have  incapacitating  pain.
