This is because the legs are easily affected by changes in blood circulation or water retention in the body. Some abnormalities in the legs will be an early warning sign of kidney damage or impaired function, according to the health website Medical News Today (UK).
Kidney disease can cause electrolyte disturbances, making your legs more prone to aches and pains.

Signs in the legs that are directly related to kidney failure include:
Swelling, edema - common signs of kidney disease
Swelling of the legs, especially the ankles and feet, is one of the most common signs of chronic kidney disease. When the kidneys no longer filter blood effectively, sodium and fluid build up in the body, leading to swelling of the legs.
Edema can result from excess fluid buildup in the legs, the National Kidney Foundation says. This is because the kidneys are no longer effectively filtering sodium and water from the blood. This swelling is usually painless, but it can feel heavy and uncomfortable and limit mobility.
Swollen legs are easily confused with venous insufficiency or heart problems. To differentiate, swelling and edema of the legs due to kidney will be accompanied by symptoms such as little urination, fatigue, and high blood pressure.
cold feet
Constantly cold feet, even in warm weather, can be a sign of poor blood flow. This is a common consequence of kidney disease. Decreased kidney function can cause anemia by reducing production of the hormone erythropoietin, which stimulates the bone marrow to make red blood cells.
A lack of red blood cells causes the blood to carry less oxygen, leading to cold hands and feet and sensitivity to cold temperatures. This condition is common in people with stage 3 or later chronic kidney disease.
Itchy feet
For people with kidney disease, itchy skin, especially on the legs and feet, is caused by the accumulation of toxins in the blood when the kidneys are no longer able to filter the blood effectively. Kidney-related itchy skin often feels deep, persistent, and is not relieved by applying medication or creams. In addition to itchy skin, patients also experience dry, flaky skin and foamy urine.
leg pain
Some people with kidney disease experience pain or cramps in their legs, especially at night. This is due to an electrolyte imbalance, which causes low levels of electrolytes such as calcium, potassium, or sodium in the blood. This condition affects muscle contraction and nerve conduction, leading to leg pain, according to Medical News Today .
