What is causing the burning sensation on the tip of my tongue and my lips going numb and metallic taste in my mouth?  I am already on a GERD diet and take medication.   I am not experiencing stomach pain or regurgiattion, but the discomfort in my mouth.
Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have mentioned that you have burning sensation on tongue, metallic taste in mouth, numb lips don't worry it can be due to Glossies or decapitation of papillae, may be due to nutritional deficiency, You can take One Capsule Vitamin B6, B12 supplements twice daily for one week Do chlorhexidine mouthwash twice daily Maintain proper oral hygiene by regular brushing and using tongue cleaner If you won't get relief then consult dentist for oral examination and Oral prophylaxis if necessary then go for investigations, Hope this will help you. Wishing you good health.
