Likely cause
Okay did you get it checked? Because burning sensation in the feet can be Because of other reasons as well like most commonly diabetic neuropathy, or increased alcohol consumption or sometimes nerve compression in the area, any fungal infection etc. In your case i am hoping you got to know about the deficiency after a blood test which showed that you have a deficiency.
What to watch for
You should be careful about signs such as:-
Loss of balance or any clumsiness
If the pain or burning spreads to ankles or calf area
Muscle weakness
Loss of any sensation in the particular area
What you can do
Next best thing is that you get yourself injected by vitamin b 12 injections on regular basis until it's normal
Or for best compliance, vitamin b12 tablets for atleast 1 month
Try to change your diet and add vitamin b12 rich food. If you are not strictly a vegetarian, kindly add eggs, fish and red meat in your diet.
If vegetarian then milk and paneer like substances can help you.
When to see a doctor
You should see a doctor physically if any of the symptoms I mentioned persists with you for more than a month.
If you want, we can discuss it more nicely in an one to one conversation if you consult me on the app.
Wish you a speedy recovery. Take care 😊💐
