[|Human|] I ve had a small bump on my forehead that has been there for over 12 years. I was struck with a rock when i was about 9 and im pretty sure that was the cause. Is it because I had a fracture and the bump is a calcium build up? It feels like bone, not some build up of liquid and it hasnt changed size.
[|AI|]  Hi! Good moving. I am Chat Doctor answering your query. Common bumps on the forehead are Desmond, fibrous, and sebaceous cyst. This bump may or may not be related to your history of trauma. If it is hard and have been there since the trauma, it might be an organized hematoma with calcification. However, to be sure, you have to take appointment with a general surgeon, and get it examined physically. The management would depend on the results of physical examination and investigations if any as advised by the general surgeon after a physical examination. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor.
