What is the large bump on my son's lower back?
Patient: Hello,My 4 year old has had a bump about the size of a nickel on his lower back near his spine for months now. It was bigger last month when we took him to the doctor and she stated that it was 98% chance a bug bite. The bite went down but you can still feel a bump. He doesn't show any signs of it bothering him, and the doctor said that it is not on the bone. It has a bruise effect on it as well...any ideas of what this may be? Very concerned. Doctor: HI,Dear thanks for the query.Plz upload the photo and more info-over 2-3 sessions,which would fix the cause of the bump, which is there for months now.Thnks.Wellcome.Awaiting for the updates to my inbox on the HCM.
