I have a very sore tongue, repeated ulcers especially on the tip.  Can it be a response to artificial sweeteners or toothpaste?   My grandmother had myasthenia gravis and complained often of a sore tongue, dont remember if ulcerated.    I have 2 sons with autoimmune diseases, type 1 diabetes and Graves disease.  I had HELLP syndrome and am concerned.
Hello and Welcome to Ask A Doctor service. I have reviewed your query and here is my advice.  As per your complaint you are suffering from RECURRENT AUTHORS ULCERS which is causing you the eruption ulcers on the tip of the tongue. It can be caused due to a number of reasons like stress, 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 and other immunocompromised conditions etc. You need to consult an Oral Physician or a general dentist in this regard to get evaluated and treated. For authors ulcer you can do warm saline gargles. Gargles with Ben Chat Doctor.  Apply numbing gel over the sore for relief from pain especially during eating. Take a multivitamin tablet for a period of 15 days. Avoid spicy, sour and acidic foods. In case if still the condition does not subside the physician can prescribe you to take a steroid course as it is the ultimate treatment in case if nothing else works. Hope I have answered your query. Let me know if I can assist you further.
