Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand.. As per your complain it seems that you have recurring apthous stomatitis leading to recurring apthous ulcers, It can occur due to a number of causes like deficiency of iron and vitamin B12, stress, dry mouth, allergic reaction, hormonal changes, acid reflux etc.. Many a times apthous ulcers can also occur without any specific underlying cause.. I would suggest you to consult an Oral Physician and get evaluated and after a proper clinical examination and investigations as per suspected cause can help in diagnosis.. The apthous ulcers that are non-responsive to other treatment are finally treated with steroids.. As of now you can do warm saline gargles, gargle with a numbing mouthwash conatining lignocaine especially at meals to prevent discomfort, take a multivitamin tablet daily for atleast months,suck ice, avoid spicy foods and drink plenty of cool water.. In case if you do not get relieved you will be advised steroids in a tapering dose under supervision of a trained oral physician.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
