Hi Dear, Welcome to HCM. Understanding your concern. Thanks for your query . As per your query the burning sensation of tongue persist even after fundoplication surgery . It seems to me that you are suffering from burning mouth syndrome. There can be two types of burning mouth syndrome one having some cause or another having no reason (idiopathic ) . There can be many reasons for burning mouth syndrome like oral thrush , lichen planus , vitamin deficiency and stress ,anxiety. I would suggest you to consult oral pathologist for proper diagnosis . Doctor may order blood test , biopsy , allergy test or salivary measurement to find out the exact cause and treat it accordingly For nor do warm saline gargles , suck ice chips ,remove dirt from tongue , avoid hot spicy food ,take ibuprofen(if not allergic) or acetaminophen for pain and irritation and rinse tongue with cold water 2-3 times a day. Hope your concern has been resolved. Best Wishes, Dr. Harry Maheshwari
