Varicose veins can easily develop when the small valves in the veins become weak. These valves generally stop blood from flowing backward through the veins. As soon as the valves are damaged, the blood pools in the veins.
This might cause twisted and swollen veins to become very visible. Varicose veins can be easily noticed, mostly because of their dark blue and purple appearance.
Sometimes, they might even bulge out from underneath the skin. There are many other symptoms, such as a burning sensation in the leg, uncomfortable legs that could feel a bit achy, muscle cramps that are more noticeable at night, swelling of the feet and ankles, and ultimately, dry and itchy skin that is visibly thinner because of the varicose veins.
