According to doctors at the Mayo Clinic, varicose veins are not usually a reason for concern, but many new therapies are available. Varicose veins arise when the valves in the vein stop functioning properly. Varicose veins may look unsightly but are not usually a medical threat.
If you have symptoms, like throbbing, cramping or swelling arising from your varicose veins, then do seek medical advice. Similarly, see your doctor if you're troubled by the appearance of varicose veins. Standard treatment used to be an operation where the veins were 'stripped out'. But this is far less common nowadays.
Instead there are many new, and less invasive, treatments. Using lasers, heat or injecting a solution that causes inflammation, which makes the veins close up, can all deal effectively with varicose veins. Crossing your legs, standing, and obesity do not appear to increase the risk of varicose veins And if you're worried about developing the condition, be aware that the main risk factors are a family history, pregnancy, and a history of blood clots.
