Hi @dipperlip1, I'm wondering if the feet going from cold to hot and changing colors is caused by Raynaud's since it's one of the symptoms. There is a discussion you might find helpful:

I did find some suggestions that might help your condition listed in the following article -- What you need to know about Raynaud's disease: https://www.medicalnewstoday.com/articles/176713

@gardeningjunkie, @degarden_girl and others may have some suggestions or information for you also.
