My doc tells me I need an neck MRI to diagnose some arm pain that may be starting in the neck. On the phone the MRI facility asked me if I had ever been involved with "metal grinding". Of course as a woodworker I've sharpened tools on a wheel, drilled holes in metal etc. I'm hoping to get more answers from the techs tomorrow but has anyone here been through this? Are they concerned about stuff in the eye or ? that might be pulled by the magnet. Any information would be appreciated -- this is all rather alarming!
