Thank you David.. Neuropathy and Erythromelalgia are taking a toll on my feet.. The toes on my right foot are purple today and that's scaring me.. it's happening far too often.. I don't think that I've mentioned the tiny muscle twitches in my calves before, but those just never stop.. They've been doing this for years, guess I've gotten use to that type of tingle sensation and don't notice it as much unless I see them.. I'm grateful for any relief from the burning feet.. As I said previously, I'm 76 years old now.. Not many folks make it this far in life without some issues and I've been very fortunate.. It's been a good life...
