Wombat,after I did a salt push last week I kidney problems for three days. The second day the dull, nagging low back started. That day and the third day I had very cloudy urine with an rainbow hued oily film on it. All this despite making sure I drank a lot of water. Is this kind of response to a salt push normal? I was afraid I had kidney damage. If I need to salt push again I am gong to come online first with you guys and have someone who has been there walk me through it.
