Pelvic congestion syndrome (PCS) is a condition characterized by chronic pelvic pain, often caused by enlarged veins in the pelvic region. This occurs when blood pools in the veins, leading to increased pressure and discomfort. Women are more commonly affected, especially those who have had multiple pregnancies. Symptoms of PCS may include aching or throbbing pain in the lower abdomen, which can worsen after standing or during menstrual periods. Diagnosis typically involves imaging tests, such as ultrasound or MRI, to identify the affected veins. Treatment options may include lifestyle changes, medication, or minimally invasive procedures.
