Hi. Since last week I got flu and i have sore throught as well. I noticed something different on my back side of mouth. There two little holes on my back side of mouth- on the left side. I never seen them before and we checked other in our family. No one has them. Why is that? Are they because of my sore throat? If yes I got sore throat so many times in my life but never seen holes on my mouth. Thank you very much in advance.
