Aging can cause several changes to your legs and feet. These include:
Muscle weakness: It can make it harder to walk and make your balance less stable
Nerve damage: It can cause numbness, tingling, and pain
Arthritis: It can cause pain and stiffness in your joints
Atherosclerosis. It is a buildup of plaque in your arteries, which can cause leg cramps (called "claudication")
Varicose veins. These are enlarged veins that can cause pain, swelling, and cramping
