Star, I know, who's counting, right?! But I think I've lost count of your caths-12? I'm at 9 now, and hoping for no more.
Unfortunately, for some people that present with certain symptoms, but don't always show the normal elevated levels, or they have normal stress test results, the cath is 'the golden standard' that is used and without having it you could be in big trouble!!
I've had 99% blockage and it didn't show up in traditional tests, Star has had some of the very same problems and more! (I'm hoping you don't mind that I speak for you, Star?)
So I wanted to wish you all the best on your next cath, Star, and hope there is something that they can help you with!!
Hugs, Teri xoxoxo
