Do You Have Unexplained Swelling In Your Left Leg? What Does It Mean?

If you have unexplained swelling in just one leg – it could be a blockage of one of the veins that continues from your leg into your pelvis.

Is your left leg bigger than your right? Is your left leg swollen but your right leg is not? Do you have pain and varicose veins in the left leg but not the right leg? This could be May Thurner Syndrome which is a blockage of the left leg vein high up in the pelvis. Even the best doctors may not be familiar with this vein condition.
