What causes severe mouth ulcers?
Patient: Hey, I currently have about 18 mouth ulcers. My mouth keeps getting more and more ulcers but days previous to it happening my mouth felt very dry and strange/ roof of mouth felt itchy as well. Among the ulcers I have another problem where the tissue under my tongue appears to be turning white as if they are covered in multiple ulcers forming together. And this is the most painful part of this.im not sure if they are ulcers as well or something differ It has been four days. Should I see a doctor? Or let it take its course? Doctor: Hi,Welcome to the HCM There can be many causes of mouth ulcers like ,1.gastric infection or ulcer2. vitamin B12 defeciency3.Vitamin C deficiency4.folic acid deficiency5.fungal infectionMouth ulcers to this extent should not be ignored and should be treated properly.My opinion would be first you get blood test done of vitaminB12   if you are vegetarian .Then you may take tab.folvite 5 mg daily and tab limcee .1 tab daily , orasep gel to decrease the ulcer .Since fungal infection and gastric ulcer has also to be ruled out for that ,get checked by physician in person and discuss further about endoscopy and vitamin B12 intramuscular injection course.Regards,Dr.Maheshwari
