You are likely suffering from the accumulation of toxic waste products in the feet, mostly uric acid crystals. They stem from an inappropriate diet mostly from too much protein, containing large amounts of uric acid) and poor liver and kidney performance. I recommend to do a series of liver cleanses, a kidney cleanse (see my book The Amazing Liver Cleanse", and appropriate dietary adjustments. The latter should be "Pitta-reducing" as described in my book "The Key to Health and Rejuvenation." Both books can be ordered from http://1stbooks.com, tel 1-888-280-7715
