Bottom of my feet burns all the time

Neuropathy: This is most probably from some form of neuropathy or nerve damage to the feet. Alternative problems may be excessive heat to the feet or possibly a side effect to a medication. See your podiatrist for a more definitive answer and treatment.

Neuropathy: Peripheral neuropathy can cause burning to both feet if exacerbated by back pain (radiculopathy) or from systemic diseases like diabetes. Best to have a podiatrist first evaluate you then possibly referral to a neurologist if necessary.
