My shoulder joints and arms ache and are so sore sometimes I can barely lift them. I think the Spleen and Liver have to do with muscles and tendons. Damp heat from sodas and fast food settles in joints and causes pain and so on. I have liver problems too. And I know kidney too. Is there a Kidney-Liver or Kidney-Spleen. One invades the other. Syndromes are seldom with one organ. There’s a Zang and Fu I have read. I also get Blood in the Spleen meridian.
