My mother has been suffering from mouth ulcers since last 10 years. This condition intensifies frequently. Her gums swell as well. These ulcers sometimes even affect her throat. Her mouth skin becomes red/white/black due to these ulcers. In the past, she has taken a lot of medications related to vitamins,
B12 etc, but had no effect. She has a lot of pain while eating any food. Please help me with this.
