I'll quick it short and succient . Hopefully I can get some advice from you lovely people !

* My foot loses color when i lift it off the ground . It turns blue and white .

* I have a bit of rough skin on the base of my foot ( probably a calus) which turns blackish  when my foot is raised .

* I have a small spot on the side of my toe which i burned with a hot water bottle 9months ago approx . The spot looks almost normal when i keep my foot on the ground ( walking etc ) but like above , when i lift my foot off the ground for say 20secs it seems to turn black .

I need advice because im really scared i might need my foot amputated . I have no diabetis .
