[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concern... As per your complaint it seems that you have Major Authors Ulcers as you told that they are large and major authors ulcers has a size more than 10 mm. Apthous ulcers that do not respond to any other treatments are finally treated by Steroids. You should take a short course of steroids under supervision of your physician. Along with it take a multivitamin tablet daily. For pain and inflammation Ibuprofen can be taken. Do warm saline gargles. Soda bicarb gargle will a help. For localized relief from pain and discomfort apply a numbing gel containing Lidocaine over the ulcers for relief especially during meals. Hope this information helps. Thanks and regards.
