Bumpy legs are usually the early manifestation of varicose veins. The veins in the legs in general, especially the superficial veins have poorly closed valves, because of genetic problems, acquired strain and other reasons of venous blood reflux, and when you stand up or when you bear weight you will have bruises exposed on your legs, called varicose veins, or superficial varicose veins, due to the disease. There is also a possibility that some people have naturally thick veins that feel like a pathological condition, and some people have more visible bruises because of their whiter complexion and thinner skin, which is not necessarily a disease. Therefore, if you have bruises on your legs, it is important to visit the vascular surgery department of the hospital in a timely manner and casually do a non-invasive ultrasound, which is more convenient, to check whether it is a disease or a normal phenomenon.
