Experiencing a whole-body burning sensation and severe hair loss requires a thorough medical evaluation, as these symptoms can be linked to thyroid imbalances, autoimmune conditions, or vitamin deficiencies (like Vitamin B12). Treatments depend on the underlying cause: For neuropathic burning, medications like gabapentin, pregabalin, or low-dose amitriptyline can soothe nerve discomfort. For thyroid or autoimmune issues, hormone regulators or targeted therapies are used. For hair loss, topical minoxidil or nutritional supplements like iron and vitamin D help promote regrowth once the trigger is managed. Please consult a doctor for a simple blood test to find the exact cause and start the right treatment plan safely.
