Hi, In this week, due to heavy work load my sleeping timing disturbed. Due to this I used to sleep by 2 or 3 am and get woke up at 6 or 7 for office routine. While doing brush i found some small red dots or blisters which I never encountered before. Plus these dots were not causing any pain unless last time I use tongue cleaner, when I clean my tongue one of red dots breaks. A small red blood came. So then I stop using tongue cleaner. I don't smoke ,or drink or chew any tobacco. I am very much scared. Is it type of mouth ulcer which can be heal by using SmileoGel or Smiley gel. One thing is I have somewhat acidity and some times digestions problem but won't constantly. Kindly guide me. PFA for images Thanks
