Is the foot pain kidney deficiency?

Foot pain may be caused by kidney deficiency or other factors.

After kidney deficiency occurs, kidney function declines, which affects water metabolism in the body, leading to water and sodium retention, causing edema in the lower limbs. After long-term walking, it oppresses the edema parts of the feet, causing local pressure to increase, stimulating the surrounding pain nerves, resulting in foot pain. However, trauma can also lead to soft tissue contusion in the heart of the foot, causing local edema, congestion, and pain.

If specific causes need to be clarified, patients should be promptly diagnosed by auscultation, visual examination, X-ray, CT examination, etc.
