why do my ovaries hurt a week before my period
Cyclical pain, pain that's related to the menstrual cycle, in a reproductive age woman, almost always has something to do with hormones and ovulation. Any abdominal or pelvic pain occurring monthly should be examined to see what changes of anatomy and physiology may be responsible for causing the pain. Many times the diagnosis of such pain is very difficult unless diagnostic studies are used or exploratory surgery such as laparoscopy is performed to look inside the abdomen. The exact timing of when and how long the pain occurs in relation to a monthly menstrual cycle can often be a clue as to what types of pathology to look for on the imaging studies or surgery.
What would cause pain occurring 7-10 days before menses each month? In the week or two prior to menses a corpus luteum cystic gland forms on one of the ovaries at the site where an egg was released from that ovary. This is a hormonally functional gland that produces progesterone primarily. The gland causes the ovary to become larger and heavier for a while until the cystic area goes away when menses starts. The other main pelvic change in the week or two prior to menses is that the veins of the pelvis often swell (dilate) under the influence of progesterone. They can become like varicose veins of the pelvis and sometimes will produce a throbbing pain, but which lasts throughout most of the last week of the cycle.
Since the pain only lasts for 3 days and it does not start 14 days before menses but rather 7-10 days, the best guess as to cause would be that the pain has to do with the enlarging ovary on the right. One would expect the pain to alternate sides if it were due to a corpus luteum gland because ovulation usually alters one month from one ovary and one month from the other. However we have seen ovulation occur pretty regularly from only one ovary even though there appears to be no disease in the other one. Pain occurs when the enlarging ovary "pulls" on any adhesions of the ovary to the surrounding tissue or simply when it stretches the ovarian capsule fairly rapidly.
Adhesions cannot be seen on ultrasound or any xrays but if you have your pelvic ultrasound during the 3 days you are having pain, One would expect to see a cystic area (small) on the right ovary if that is where you are having pain.
December 14, 2010 Posted by Nathan Michael Before one or two weeks of the, a corpus luteun cystic gland will be formed on one of the from which the egg would have released. Primarily is produced from this hormonally efficient gland. The gland will make the ovary to grow big and also heavy for sometime till the cystic area goes out when the menses commence.
The other important change in the pelvic prior to one or two weeks of the menses is that the swelling of veins of the pelvis under the pressure of progesterone. They will also turn like varicose veins of the pelvis and occasionally it gives a burning pain, that will remain completely and mostly till the last week of the. When the pain remains only for three days and does not commence before 14 days of the menstrual time and starts only 7-10 days earlier, the best assumption for the pain is enlargement of the ovary situated on the right side. The pain on the alternate sides can be expected if there is due for the corpus luteum gland since the generally alters 1 month from one ovary and from the other the next month.
However, there are many cases where the ovulation happens very recurrently from one ovary even though there is no illness found on the other ovary. Pain will happen for the woman when the ovary pulls on the adhesions during its enlargement to the nearby tissues or when the expansion of the ovarian capsule occurs. When the X-ray or ultra sound test is taken, adhesions will not be visible. But when the for the pelvic is taken during the days of pain, then the small cystic spot on the right ovary where the pain is can be seen.
