I had numb feet too. I got it checked and they diagnosed it as peripheral neuropathy. This is basically a condition of the nerves which is a side effect of long term kidney disease. I was put on some drugs but it did not help. The neurologist said there is nothing much that can be done about it. So, I stopped the medication after a couple of months.The numbness has gotten worse over the last year.Hope that helps!ThanksKamalhttp://kamaldshah.com
