7. Varicose Veins

Varicose veins are close to the surface of the leg and are primarily a cosmetic issue for most sufferers of this condition. However, they can also increase the risk of superficial thrombophlebitis, which is a blood clot in a superficial vein. Varicose veins occur when valves within the veins stop functioning properly, and blood is allowed to flow backward through the vein rather than flowing towards the heart. This can lead to blood clots in the shallow veins, which are often very painful. To prevent this from occurring, you should avoid extended periods of inactivity in which you do not move your legs.
