Hi.. Thanks for the query.... I have gone through your query and can understand your concerns.. As per your complain and the symptoms of hurting of tongue tip and edges and soreness of inner lips and gums can be due to Apthous Stomatitis or inflammation inside mouth.. It can be caused due to a number of reasons like Stress, Dry mouth, Nutritional Deficiency [Iron, Vitamin B12 and Folic acid] , hormonal changes, acid reflux, tongue trauma due to some sharp teeth or tongue biting habit, excessive intake of sour and citrus foods, uncontrolled diabetes etc.. You need to consult an Oral Physician or a general dentist in this regard to get evaluated and treated.. 1.As of now you can do warm saline gargles 2.Gargle with numbing mouthwash containing Lignocaine.. 3.Gargles with 1:1 solution of benadryl and milk of magnesia can help.. 4.Take Vitamin B complex capsule for a period of 15 days.. 5.Avoid spicy, sour and acidic foods.. 6. Suck ice popsicles or do cool water rinses.. In case if still the condition does not subside the physician can prescribe you to take a Steroid course as it it the ultimate treatment in case if nothing else works.. Hope this information helps.. Thanks and regards.. Dr.Honey Nandwani Arora.
