i know this is going to be a dumb question but my wife had an aneurysm which resulted in a craniotomy and two clips. thank God she is doing well and back to normal with no apperant residual effects. no side effects except one. She is noticing bone growth in the bore areas and some other areas. you can feel them as well. they are not noticable but they are getting bigger and she is starting to get concerned. She calls them her horns. i have looked everywhere to try and get information. are they dangerous. can they be harmful. your advice and recommendations would be appreciated
