Pelvic : Pelvic congestion syndrome is a diagnosis of exclusion, meaning typically your doctor will investigate common causes of pelvic pain first. It can be a difficult diagnosis to make. True pelvic congestion syndrome is a problem that causes pelvic pain that is not fixed in one area (it may hurt on the left side one day and on the right side another day). It is usually made worse by prolonged standing, and causes pain during and after intercourse. It is caused by dilation of blood vessels in the pelvis. The vessels by become dilated as a result to being compressed by an enlarged uterus that has shifted inappropriately, a fibroid or from compression by the pelvic muscles. The causes the blood in the veins to be stagnant and does not move back to the heart quickly. The distension of the vessels from compression causes pain. It can be diagnosed on ultrasound, ct scan, MRI or during surgery. If the pain is truly from the pelvis, it may be caused by other problems such as adenomyosis (thickening of the uterine muscle or something else such as endometriosis. A hysterectomy can improve pain from pelvic congestion and other problems related to the pelvis. For women who have chronic pelvic pain that are done with child bearing, a hysterectomy may be helpful.

See Specialist: Consider imaging studies for your spine if you believe your pain is sciatica or sacra-iliac in origin. Pelvic congestion syndrome can mimic sciatica occasionally but it is typically a diagnosis of exclusion, meaning everything else has been ruled out first.
