Absolutely, this could very well be the case. This is one reason why a pre-fast Liver Flush is recommended. The good news is that a Liver Flush is easy and we have a great Liver Flush Forum here at the Curezone. Your friend is right though and your symptoms that sound like they could resemble hives are related to a congested liver. I would recommend the most popular flush which is the Hulda Clark Flush which will get things moving along and then if you feel there is more need to keep flushing, you have herbal options to use to soften stones or slower flushes using apple juice. Look at the recipes at this url and check out the forum and make your choice which flush to try first.
