Neurobion Nerve Pain Relief Cream may provide temporary relief from the burning sensation in your mother's feet, but it is unlikely to be enough on its own if the symptoms are caused by diabetic nerve damage. The cream contains capsaicin, which can help reduce burning, tingling, and nerve pain when applied regularly. However, it does not treat the underlying nerve damage or improve diabetes control. Since the burning is worse at night, diabetic peripheral neuropathy is a possible cause and should be assessed by her doctor. Good blood sugar control is the most important step to slow nerve damage. If the pain is persistent or affects her sleep or daily activities, her doctor may recommend prescription medicines specifically for nerve pain, such as pregabalin or duloxetine. She should also examine her feet daily for cuts, blisters, or ulcers and wear comfortable footwear. If the symptoms are severe, worsening, or associated with numbness or weakness, she should seek medical advice promptly.
