<human>: about 2 months ago, I started having burning sensations on the outside of my big toes and the ones close to them.  I notice my finger tips and palm of my hands are sometimes very dark (I am african descendent).  the finger tips are sensative as well. what is the cause of this?
<bot>: Hi, Thank you for posting your query. I have noted your symptoms, and they are suggestive of peripheral neuropathy (disease of the nerves of feet and hands). You should get evaluated by a neurologist. A nerve conduction study would confirm the diagnosis. Underlying causes to be excluded are diabetes, vitamin B 12deficiency, etc. As of now, you can take pregabalin capsules for relief of symptoms. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health, Chat Doctor. Ly/
