Hello there...I can understand your concern. Ulcers over the mouth can be due to many reasons like vitamin deficiency, herpes simplex infection, candidiasis, pemphigus, oral lichen planus. It is important to differentiate between the conditions as the mode of treatment is different in each condition. So kindly consult a dermatologist for further evaluation.
