Burning sensation in foot has many causes. Most common is due to change of footwears, dry feet etc. A recent weight gain or even weight loss can also cause burning sensation in foot. Mostly the problem resolves by itself without medicines but takes few weeks. You can give a trial of hot and cold fomentation to foot alternatively for a week. If problem persists it's better to consult an orthopaedician and get his advice accordingly.
Get well soon.
