My 5 yr old has a swollen vein on his left cheek inside his mouth. He s been to the dentist recently and they saw nothing. She thinks he may have a canker sore or something. This pain has been bothering him on and off for a yr now. I don t think it s an abcest tooth because his dentist would have seen that on X-rays. Is there anything else it could be?
HI...it could be a hematoma of the cheek. But one thing which is not falling into the groove is that there is pain which is not usual in hematomas.  I suggest you consult a pediatric surgeon and get a biopsy done. We will know the diagnosis confirmed. Regards -
