Burning sensation in foot and leg.

My friend has that problem. She thinks it could be to do with her varicose veins.
She has already had the nerve conduction test, which came out normal (I think) and on Monday goes for an MRI on her back. She had an operation on her back a few years ago , from what she tells me "to release a trapped nerve."
Then she returns to the neurologist to see what he thinks.

Yup - all the time. Nerve damage.

Peripheral Neuropathy ? which I think is another way of saying nerve damage.
