Think when young as both husband and Blair were,there wasn't the knowledge out there about the Tinnitus and headsets use long term .Same as youngsters with music blasting away in there ears ,as they do today ,till further along down the road ,then for lots T show it's ugly head .Yes common sense should prevail ,educate these youngsters every chance you can ,if you can get it through to just one ,you've made a difference .
Hope everything turns out well for you ,MRI are quite normal these days ,lots have this done ,so don't you go worrying any okay ,I've had it done .No problem .
