I chose however, not to wear my Tens Machine that I use for back pain. It’s the standard little black box attached to you somewhere with little LED lights and lots of trailing wires. In an airport. Where security is high and some people are jittery. Suicide bomber anyone?! I wasn’t up for dealing with that!
My mum did buy me (bless her and thank you) a small tens that you stick to your back- the control unit sticks to you so no wires and no false alarms. I mentioned it to security at the point of hand baggage screening and pat me downs and they literally swabbed it with their magic wands and that was that.
The actual machine, if anyone is interested, was bought from Boots the Chemist in the UK.
