I recently saw an osteopath who told me that my kidneys, which are supposed to be able to move up and down, were only moving up. As a result, kidney tubes and spermal tubes were entangled, which could be one cause of infertility that we’ve been experiencing. She freed up my kidneys, but wasn’t sure what I could do to maintain kidney flexibility and mobility. Any ideas about how to maintain this? Does it result from a yin or yang deficiency? Or something else?
