I have noticed sometimes a bluish tinge to my fingernails and a bit of a cold and tingly feeling in feet and hands. Sometimes almost like pins and needles.
I normally have blood pressure on the lower side, but it’s been really low while I’ve been on the diet, (100/60 last Friday). Hard to know what comes from what though isn’t it! I totally understand about avoiding going to the Dr, it costs a fair bit here and I would rather spend that money on things I need for this diet too.
However, you know your body best, and if you’re really worried, it may be best to just bite the bullet and go!
Good luck, hope you start feeling good soon 🙂
