Hi, Thanks for your query. Most likely cause for burning sensation in feet is peripheral neuropathy. I would recommend you to get vitamin B 12 levels done. I would like to know what kind of job you are doing like playing musical instrument/job which makes feet vibratory - then there are chances of Raynaud s phenomenon. In this condition, people will experience numbness in feet with similar cold feeling. Cold stimulation test confirms it. We should also rule out hypothyroidism where few patient experience similar symptoms. Get T3, T4, and TSH done. Sometimes vascular occlusion of lower limb vessels also causes similar symptoms. To diagnose it we need to do Duplex ultrasound of lower limb vessels. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
