I had bladder cancer 15 years ago, but only last year I had major surgery to allow me to not have a permanent catheter. I now have to use intermittent catheter. But very recently I’ve needed to go through security for a concert and they didn’t know what to make of them. They thought it could be drug or alcohol related. After a lot of embarrassed explaining they finally let me go with them. Is there another way I can get through security in an easier way, as I don’t want to feel like I have to explain in so much detail again. Or a easier way to prove that they could be medical. Thanks
