Burning Feet Syndrome is a condition characterized by persistent burning sensations in the feet, often accompanied by warmth, tingling, or numbness. It is caused by nutritional deficiencies (particularly vitamin B5 or pantothenic acid), diabetes-related nerve damage, or peripheral neuropathy. The Vitamin B5 (Pantothenic Acid) test is the most important test for diagnosing nutritional causes of Burning Feet Syndrome.

Burning Feet Syndrome is caused by nutritional deficiencies, nerve damage, or metabolic conditions affecting the peripheral nerves in your feet. The most common nutritional cause is vitamin B5 (pantothenic acid) deficiency, though this is extremely rare and typically occurs with other vitamin deficiencies. Diabetes is another major cause, as high blood sugar levels damage small nerves over time, leading to diabetic neuropathy. Other causes include thyroid disorders, chronic kidney disease, alcohol abuse, and certain medications that affect nerve function.
The Vitamin B5 (Pantothenic Acid) test is the most important test for Burning Feet Syndrome because it detects pantothenic acid deficiency, a rare but treatable nutritional cause of burning foot sensations. This blood test measures your B5 levels to determine if supplementation could relieve your symptoms. Since burning feet can have multiple causes, your healthcare provider may also recommend comprehensive metabolic panels to check blood glucose levels for diabetes, thyroid function tests to rule out thyroid disorders, and additional B-vitamin tests (B12, B6, folate) since nutritional deficiencies often occur together.
You should get tested if you experience persistent burning, tingling, or numbness in your feet that interferes with daily activities or sleep. Testing is especially important if you have diabetes, follow a restrictive diet, consume alcohol regularly, or have a history of malabsorption conditions. You should also get tested if over-the-counter treatments have not relieved your symptoms after several weeks, or if the burning sensation is worsening or spreading to other areas. Early testing helps identify treatable causes before permanent nerve damage occurs.

What this means
Your Vitamin B5 level is slightly below the optimal range, which may be contributing to feelings of fatigue or reduced energy throughout the day. While B5 deficiency is uncommon, suboptimal levels can affect your body's ability to efficiently convert food into energy and may impact stress hormone production.
Recommended actions
Include B5-rich foods like mushrooms, avocados, eggs, and chicken in your daily diet
Consider a B-complex supplement or pantothenic acid supplement after consulting with your healthcare provider
