The phenomenon of soreness in the feet of the elderly is due to the relatively low activity of the elderly, which can easily lead to the loss of calcium in the bones of the feet, causing the elderly to suffer from osteoporosis in the feet, resulting in a decrease in local absorption of nutrients, leading to muscle nutrient metabolism disorders, resulting in soreness and pain. In addition, the bones of the feet of the elderly are also prone to degeneration, making the elderly suffer from osteoarthritis and chondromalacia in the ankle joints, which can also produce clinical phenomena such as pain and swelling, affecting normal activities. If the elderly have old damage to the muscles in the feet, they will also have this performance. Therefore, when elderly people have sore feet, they can make a clear diagnosis and then take symptomatic treatment.
