For the past several months, whenever I go through a metal detector my battery pack for my NeuroStim doesn't show up but something on my left knee does. Makes me look silly when I give them my card and tell them what to look for and nothing in that area shows up. Lol
Oh and lately I set off the alarm at Wal-Mart. Not every time but enough that it caught my attention. Lol
When I feel my hip the battery pack is still there.
Oh and the knee? I have never had anything done to it other than steroid shots. Going to have orthopedic surgery in Febuary on that knee but still a bit strange that it sets off alarms.
