Patients with nephrotic syndrome who experience leg pain mostly have conditions unrelated to nephrotic syndrome itself. It could be due to diseases of the skeletal or muscular system. However, some patients might experience leg pain due to thrombosis caused by nephrotic syndrome, leading to ischemia in the limbs. Also, long-term use of corticosteroids can lead to necrosis of the femoral head, osteoporosis, and pain. Therefore, treatment should be targeted based on the cause, such as using drugs to dissolve clots or interventional surgery for those with thrombosis. In severe cases of femoral head necrosis, a femoral head replacement surgery might be necessary, and it is important to supplement with calcium regularly.
