[|Human|] My 6 year old nephew had cranial surgery for lamdoid synystosis in December and this morning he had a nosebleed and this afternoon a large lump developed on his forehead with no trauma occuring.  Is it possible there is a connection between the surgery and the lump developing?
[|AI|]  Welcome to Chat Doctor .1. Possibilits of the previous surgery can not be ruled out.2. In case of any infection / inflammation to the post-operative site with edema may appear as lump.3. I would recommend you to see the treating doctor / pediatrician as soon as possible both for the lump and nasal bleed.4. In post-operative case delay is not accepted - as it may complicate. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
