I wear an insulin pump and have never had much trouble with security--it does not beep the metal detectors, as it is all plastic. I always carry a prescription and that usually does it.
It seems TSA is changing the rules and if you wear any medical device with a liquid (mine holds about 3 teaspoons of insulin) you must alert them and be patted down. They will also be going through your suitcase. As they are not allowed to touch the pump, I must swab it down and then have my hands checked for explosives.
Does anyone else think this is highly UNFAIR? I will take an extra 20-30 minutes to go through security now.
