Sorry to hear that.
Recurrent mouth ulcers are sometimes associated with certain connective tisue disorders like lupus, Sjogren's, Behcet's disease, or bullous pemphigoid.
Behcet's disease neds to be given special consideration due to her recurrent episodes of oral ulcers.
These conditions are diagnosed by a rheumatologist.
Otherwise, this is likely related to aphthous ulcers.
Potent steroid mouth rinses like triamcinolone acetonide in Orabase, fluocinonide gel covered by Orabase, amlexanox 5 percent oral paste are helpful in providing relief.
Hi thank you for your response.
Are those available without prescription?
and how serious are those disorders. Is there anything that she can eat that can help?
These medications require prescription.
These disorders are due to her hyperactive immune system, which is causing iflammation of the mucous membrane ( auto immune disorder) like in the mouth.
She can eat antioxidants more like fruits, vegetables etc.
Avoid hot & spicy food, coffee, alcohol.
