I have a bruning in my leg is that normal?

NEUROPATHY. Burning in legs and feet mean that you have peripheral neuropathy, many things may cause that, the most common is diabetes especially with poor control of blood sugar, other causes may be vitamin B12 deficiency, others include lead or heavy metals toxicity, the best way to diagnose is emg/ncv which showed injury of the sensory nerves of the lower extremities, treatment is to treat the cause.
No. Could be brain or peripheral nerves--need good exam and testing-- is it intermittent or continous? How long it last? Previous injury? Compression to the site?
