Hello! Here's the thing. First of all, lumbar muscle strain is the name of western medicine, and kidney deficiency is the name of Chinese medicine. Under different medical systems, they do not refer to the same situation.

But there is a certain connection between the two. Lumbar muscle strain can be divided into acute and chronic types, or new symptoms (shortly after strain occurs) and chronic diseases. The symptoms of the former are related to cold, dampness and blood stasis in traditional Chinese medicine. The latter has a long course of disease, which often leads to kidney deficiency or blood stasis in traditional Chinese medicine. As for kidney yang deficiency or yin deficiency, it should be said that it is possible. To judge accurately, you have to see a doctor.

I wish you the best of health!
