What Happens If You Get a Blocked Vein in Your Leg?

A blocked vein in the leg often leads to a condition called peripheral artery disease. Once the vein is blocked, blood flow to and from the leg is compromised, which can then lead to multiple complications including pain in the legs, notes WebMD.

Vein blockage in the legs can happen when there is a buildup of plaque in a given area. This buildup can be caused by fat or cholesterol, according to MedlinePlus. Unless treated quickly, vein blockage may lead to gangrene or death of tissue in the area affected. Individuals who have severe cases of gangrene may have no other option for treatment except amputation.

Most cases of vein blockage do not produce symptoms. However, in some individuals may experience painful sensations in the legs. Such individuals may have leg wounds that do not heal as fast as they should. Pulses in the feet may grow weak or fade away.

These individuals’ skin may become pale or bluish in color. Other common symptoms associated with peripheral artery disease include poor nail growth of the toes, erectile dysfunction, lower temperature in one leg and loss of hair in one leg.

The easiest way to prevent or treat this condition is by engaging in certain types of exercises. In severe cases, treatment may involve medication, angioplasty or surgery.
