If you have Chronic Venous Insufficiency, your ankles may swell and your calves may feel tight. Your legs may also feel heavy, tired, restless, or achy. You may feel pain while walking or shortly after stopping.
Chronic Venous Insufficiency may be associated with varicose veins. Varicose veins are swollen veins that you can see through the skin. They often look blue, bulging, and twisted. Large varicose veins can lead to skin changes like rashes, redness, and sores.
Chronic Venous Insufficiency can also cause problems with leg swelling because of the pressure of the blood pooling in the veins. Your lymphatic system may also produce fluid, called lymph, to compensate for Chronic Venous Insufficiency. Your leg tissues may then absorb some of this fluid, which can increase the tendency for your legs to swell. In severe cases, Chronic Venous Insufficiency and the leg swelling can cause ulcers to form on the lower parts of the leg.
