:confused: I'm 20 right now. doing my third year MBBS. since my childhood days i used to get repeated aphthous ulcers on and off.. when i got it for the first time, when i was a kid, my mom used to give me home treatment. since then, whenever i get aphthous ulcers, i used to follow that... but i'm not sure why i get this... I thought that it was due to b complex vitamin deficiency but i used to take it on and off... is there any suggetions about this????
