My mother (71) and daughter (14) have it, and their diagnoses was primary erythromelalgia. Peripheral neuropathy is one of the symptoms, in addition to chronic dry mouth, Raynaud's, and feet (and sometimes hands) that get very red and hot. I have symptoms of erythromelalgia as well, but I don't have the peripheral neuropathy at this point. I'm hoping to bring my daughter to Mayo's erythromelagia clinic within the next year. Just last week, I watched a video on their web page that explains how to, and how not to, relieve the symptoms of peripheral neuropathy.
