My work insurance is the same way, fought them for fifteen years trying to get employer to Change there ways". Then I found out that the VA hospital does WLS, took a year and a half finally got it done 2 1/2 months ago. If you are a Veteran look into it.
I had a drain it was attached to a tube that was above my insisions and had a squeeze ball at the end of it. They took it out on the third day. I remember the doc said before he took it ou that this won't hurt but it might feel a little weird. He was right hard to explain I just don't want to do it again. Lol..
