Poor circulation can cause redness in the toes, tingling sensations and foot cramps, according to FootSmart. The toes may also turn blue to purple in color. Skin discoloration is often due to venous insufficiency, a condition in which blood flow between the leg veins and the heart becomes restricted.
Additional symptoms of poor circulation include throbbing in the limbs, cold hands, cold feet and numbness, according to Healthline. Circulation problems can be caused by multiple factors that include blood clots, varicose veins and medical conditions such as diabetes. It is always important for individuals experiencing potential symptoms of poor circulation to consult with a physician, as certain conditions such as blood clots can lead to life-threatening complications.
