Pelvic congestion syndrome is a type of vascular disease that develops when the veins in your pelvic region don't efficiently push blood back to your heart. As a result, your blood can pool in your veins and make them swell and bulge, much like varicose veins that form in your legs. Venous insufficiency usually develops when the small valves in your veins don't function correctly, and your blood moves slowly or even flows backward.
Your risk of venous insufficiency increases if you're overweight or pregnant. You have a higher chance of developing the condition if you have a family history of venous insufficiency or if you smoke. It also occurs in women who are otherwise completely healthy.
Pelvic pain in women can have many causes, in first instance the best person to talk to is a gynaecologist who can diagnose the cause of the problem. If you are suffering with pelvic congestion syndrome, they will refer you to an interventional radiologist who is expert in the minimally invasive technique of embolization used to treat pelvic congestion syndrome.
