I have buerger's disease so far only my fingers which have ulcers and burn and very painful. My doctor at the hand clinic in Louisville told me to soak in small amount of bleach and water and put zinc oxide cream on and bandage. It hasn't seemed to help. I am still struggling with the smoking issue which I know doesn't help. I have got to quit or I am going to lose some fingers. I cannot find a doctor here in Hopkinsville who knows anything much about buerger's disease but there has to be something better to put on the ulcers caused by the disease. I was told it is aa bad blood circulation issue and that is the reason why they get purple, very cold and eventually rupture into ulcers. If you know more, please let me know.
