I don t think she has diabetes she is going to duke university medical dept for some help. Do you know of any reason this might be happening to her thanks Lynn
[|AI|]  Hello I have studied your case, These symptoms could be due to vascular occlusion around your foot. Colour Doppler may help in diagnosis. Vascular occlusion may be common in smokers. Another possibility of Reynolds phenomenon leading to blackening. You need to immediately consult your treating doctor and do required investigations. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care.
