Menstrual pain and pelvic pain can be caused by other things. Pain due to endometriosis is often associated with similar symptoms such as cyclic pain with periods (increased pain at the same time of the menstrual cycle each month) painful intercourse, irregular bleeding and pelvic pressure.
Endometriosis is the most common finding associated with pain in women of reproductive age. It is arguably the most common cause of pain, and it deserves most of the bad press it receives. In many cases, endometriosis causes pain associated with the menstrual cycle but other symptoms can be a result of endometriosis. Endometriosis pain can be frequently localized by the patient to the pelvic area that is involved by the disease. Some patients can describe exactly where their disease is by the nature and location of their pain.
