As a vegetarian, Vitamin B12 deficiency is common because B12 is primarily found in animal products. To treat this, you can take daily oral Vitamin B12 supplements (Methylcobalamin or Cyanocobalamin) at a dosage of 1000 mcg to 2000 mcg, which are highly effective for mild cases. If your deficiency is severe or causing symptoms like extreme fatigue or tingling, your doctor may prescribe intramuscular B12 injections initially. Please consult your physician for a simple blood test to determine the exact dosage. Additionally, try consuming B12-fortified foods like cereals and plant-based milks.

A constant burning sensation and pain in your feet are common symptoms of peripheral neuropathy, which can be caused by diabetes, vitamin B12 deficiency, or nerve irritation. Because the correct treatment depends entirely on the underlying cause, there is no single over-the-counter medicine to cure this. I highly recommend visiting a doctor for blood tests to find the root cause. Depending on the diagnosis, they may prescribe nerve-pain medications (like gabapentin or pregabalin), targeted vitamin supplements, or pain-relieving creams. For temporary relief, avoid tight footwear, keep your feet cool, and seek a professional medical evaluation.
