Aching, tired or heavy legs?
It's probably varicose veins
Aching, tired or heavy legs are very common particularly at the end of the day or after exercise or prolonged walking. Many people think this is normal but it usually means you have varicose veins. With varicose veins the one way valves that keep blood moving from the legs back to the heart don't work properly and this causes blood to pool in the lower legs. The resulting stretching of the abnormal varicose vein causes the aching.
If you have these symptoms it is best to see a phlebologist (vein doctor) and have an ultrasound scan to assess whether treatment is necessary. Modern treatments like endovenous laser and ultrasound guided sclerotherapy are simple and don't require anaesthetic or time off work.
