Varicose Veins
In some cases, restless legs syndrome can be caused by poor blood flow in your legs. More specifically, weak veins that become uncomfortable and distend can be a major risk factor. These varicose veins are usually blue in color and enlarged. This would be a clear symptom of venous insufficiency. Treating varicose veins has been shown to be effective in improving certain signs of restless legs syndrome. This includes the use of medications and scleropathy.[3]
