What is pelvic pain?
Pelvic pain is a common complaint among women. Its nature and intensity may fluctuate, and its cause is often obscure. In some cases, no disease is evident. Pelvic pain can be categorized as either acute, meaning the pain is sudden and severe, or chronic, meaning the pain either comes and goes or is constant, lasting for a period of months or longer. According to the American College of Obstetricians and Gynecologists, pelvic pain lasting longer than 6 months and showing no improvement with treatment is known as chronic pelvic pain. Pelvic pain may originate in genital or extragenital organs in and around the pelvis, or it may be psychological, which can make pain feel worse or actually cause a sensation of pain, when no physical problem is present.
What causes pelvic pain?
Pelvic pain may have multiple causes, including:
Inflammation or direct irritation of nerves caused by acute or chronic trauma, fibrosis, pressure, or intraperitoneal inflammation
Muscular contractions or cramps of both smooth and skeletal muscles
Psychogenic factors, which can cause or aggravate pain
Some of the more common sources of acute pelvic pain, or pain that occurs very suddenly, may include:
Ectopic pregnancy (a pregnancy that occurs outside the uterus)
Pelvic inflammatory disease (an infection of the reproductive organs; also called PID)
Twisted or ruptured ovarian cyst
Miscarriage or threatened miscarriage
Urinary tract infection
Ruptured fallopian tube
Some of the conditions that can lead to chronic pelvic pain may include:
Uterine fibroids (abnormal growths on or in the uterine wall)
Adhesions (scar tissue between the internal organs in the pelvic cavity)
Endometrial polyps (protrusions attached by a small stem in the uterine cavity)
Cancers of the reproductive tract
This long-term and often unrelenting pain may cause a woman's defenses to break down, resulting in emotional and behavioral changes. This is often termed "chronic pelvic pain syndrome."
What are the different types of pelvic pain?
The following are examples of the different types of pelvic pain most commonly described by women, and their possible cause or origin. Always consult your health care provider for a diagnosis.
Type of Pain
May be due to an inflammation
May be caused by spasm in a soft organ, such as the intestine, ureter, or appendix
Sudden onset of pain
May be caused by a temporary deficiency of blood supply due to an obstruction in the circulation of blood
May be due to inflammation of the appendix or an intestinal obstruction
Pain involving the entire abdomen
May suggest an accumulation of blood, pus, or intestinal contents
Pain aggravated by movement or during examination
may be a result of irritation in the lining of the abdominal cavity
How is pelvic pain diagnosed?
Diagnostic procedures and tests will be performed in order to determine the cause of the pelvic pain. In addition, your health care provider may ask you questions regarding the pain such as:
When and where does the pain occur?
How long does the pain last?
Is the pain related to your menstrual cycle, urination, and/or sexual activity?
What does the pain feel like (i.e., sharp, dull, etc.)?
Under what circumstances did the pain begin?
How suddenly did the pain begin?
Additional information about the timing of the pain and the presence of other symptoms related to activities such as eating, sleeping, sexual activity, and movement can also help your health care provider in determining a diagnosis.
How is pelvic pain diagnosed?
In addition to a complete medical history and physical and pelvic examination, diagnostic procedures for pelvic pain may include:
Culture of cells from the cervix
Ultrasound. A diagnostic imaging technique which uses high-frequency sound waves to create an image of the internal organs.
Computed tomography (CT). A non-invasive procedure that takes cross-sectional images of the internal organs to detect any abnormalities that may not show up on an ordinary x-ray.
Magnetic resonance imaging (MRI). A non-invasive procedure that produces a two-dimensional view of an internal organ or structure.
Laparoscopy. A minor surgical procedure in which a laparoscope, a thin tube with a lens and a light, is inserted into an incision in the abdominal wall. Using the laparoscope to see into the pelvic area, the health care provider can determine the locations, extent, and size of the endometrial growths.
X-ray. Electromagnetic energy used to produce images of bones and internal organs onto film.
