<s>[INST] I have a small pea sized bump on my forehead. I noticed this about 10 years ago. At that time I had it checked by my doctor and a specialist who both said it was nothing and not to worry about it. Over the years I ve noticed it get bigger..not so much in size ..just more out of my head. I had x-rays done on it and they told me it was a bone. Again not treating it as anything life threatening. I done understand how a bone could grow out like a bump. Could this be something other than my bone? It causes me no pain.I m just worried it s something else and the doctors are wrong. [/INST] kindly show me X rays & photograph of the bump on your forehead before I can give any opinion.It could be anything ranging from a subacious cyst to a osteoma. </s>
