I recently had neurosurgery and now have titanium mesh and screws in my head (gives new meaning to having a screw loose!). I've read the "rules" but also know TSA agents don't always act consistently. Has anyone seen someone or experienced going through security with a similar situation and, if so, other than needing a patdown has there been any trouble? I am flying in 3 weeks and trying to make sure I am prepared. Thanks so much for your help!
