Swelling, formally known as edema, is a common condition caused by fluid buildup and retention around the hands, feet, legs, and ankles. While swelling can be due to medication regulating blood pressure or general inflammation, this fluid retention is also commonly caused by vein diseases like varicose veins. Patients with edema may notice limbs are more swollen than usual. They may also experience cold and numb feet, and open sores and ulcers on the feet and legs. Treatment is available to relieve the swelling and discomfort. Additional therapies and treatments address symptoms such as skin texture changes, open wounds, and limited range of motion. If caused by an underlying issue with the venous system, recommended procedures include radiofrequency ablation, Varithena™ microfoam ablation, sclerotherapy or other vein treatments.
