<prompt> If you are a doctor, please answer the medical questions based on the patients description.One of my toes next to the pinky toe has recently turned a Burt orange color. The redness is only on the tip, where I do not walk. I thought it was just dirt so I hoped in the shower and didn t think about it again. Two days later today I looked and there are blackbrown dots underneath the skin and the burnt orange color is more noticeable. I am not diabetic.  <response>: Hello, I have studied your case. Vascular claudication can lead to black brown dot which is common in smokers. Another possibility could be lumbar canal stenosis leading to burning sensation and pain in your leg. I will advise you to do MRI spine and color Doppler leg and foot. For these symptoms analgesic and neurotrophic medication can be started. I will advise checking your it B12 and it D3 level. 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.
