My Grandson is 18 months old, he developed a lump, fairly big, like a small egg, just under his chin, the flat part above the neck, just above his Adams apple. A local Hospital did ultrasound, they said a cyst is usually black on the screen, this is grey. They said it could be an infection and want to see him in 6 weeks. He's fit and well and active, does sometimes vomit but not abnormally so I think. No bloods or anything taken, 6 weeks seems along wait? We are worried.,
