Hi. I am going out of my mind with worry. My 8 year old has developed swollen upper gums over the last couple of months. We seen the dentist last week who said they were really quite bad and suggested seeing the GP if no better in a week. I'm terrified it's leukaemia or some other awful condition. I think his glands are up also and his face is puffy in the mornings. I tried phoning the GP today but couldn't get an appt. Anyone experienced anything similar?
