[|Human|] hello, I noticed about three days ago a small vertical indentation on the top of my head. It actually seems to get larger and smaller throughout the day. I have found the more I touch it the deeper it gets. It is not painful at all. I get random headaches (sinus). I am a 53 yo woman.
[|AI|]  Hello ! Thank you for your question on Chat Doctor! I think that this may be from your birth. You should know that the bones of the scull are divided and get fused after 12 months of life. During the fusion, there may be imperfections and cause indentations in the fusing sites. I think that it has been there for a long time, and you may have not noticed this. Another argument in favor of this, is that you don't have pain. But I would recommend consulting with your GP, have a full blood work (for hematological problems or inflammation) and a scull x-ray in two positions. Hope to have been of help! Thank you for using Chat Doctor! Greetings!
