Walking has leg weakness. What happened?

It is suggested to go to a regular hospital for an examination, which may not be as simple as calcium deficiency and lack of exercise. I agree with Guan Zhou Fengyun that it may be related to the lumbar vertebrae, and more seriously, it may be related to the kidneys. Don't think that young kidney function is good. A friend of mine (also a woman) was diagnosed with severe renal failure in junior high school, but it took half a year and was finally cured. However, due to taking too many kinds of drugs, there have been a series of problems: atavism, thick body hair growing everywhere; Vision loss, etc.

Therefore, it is suggested that the landlord go to a regular hospital for examination and treatment as soon as possible.
