my daughter had tonsils out 3 yrs ago, and now on one side has a hole in the tissue in the back of her throat.is this serious? She also has a cold right now, and when it started, and her throat was sore, that was when I noticed this. But she still has the head cold, and NO sore throat so I want to know if I can wait to have this hole looked at, so she doesn't contract something else at the doctor's office - as there are always 20 sick kids running around.......
