@dr.timothy.health.coach: Why are my feet burning even when my vitamin B12 levels are normal? 🔥 Serum B12 doesn’t always tell the whole story. Burning feet can have several causes, including nerve problems, poor blood flow, nerve compression, inflammation, and diabetes. In some situations, additional testing such as methylmalonic acid (MMA) may help assess whether B12 is functionally available to the body. If you’re wondering what causes burning feet, don’t rely on one test alone—persistent or worsening symptoms should be discussed with a healthcare professional. #burningfeet #neuropathy #nervehealth #vitaminb12 #peripheralneuropathy
