[|Human|] Hi there, my little boy fell off his push bike a week ago and the handlebars dug into his side around his appendix area.  It didnt puncher the skin but it did graze it.  It all healed well but tonight he came to me and said it was hurting and when I felt the area, it feels like two hard cysts under the skin.What could this be?Thanks Belinda
[|AI|]  Hi Belinda, Thanks for placing your query here. I can appreciate your concerns about your son. Handlebar injuries are very common in child Chat Doctor. There are two possibilities of the painful twin swellings under the skin.1/- Hematoma (blood collection under the skin)2/- Abdominal wall hernia. Getting a Pediatric surgeons' opinion & Ultrasound of abdomen will clarify the matter. Hope I have answered your query. If you have any further questions I will be happy to help. Best regards.
