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.
