Hi. I'm a C6-7 quad who has been using these catheters for about as long as I can remember. And up until a few weeks ago they worked great and i never used skin prep. Then they started blowing. They didn't stay on my skin. I started using skin prep and now they are barely staying on. If I "kick off" too much they blow. My confidence is gone. Has anyone else had problems with the Freedom Clear LS recently? Any recommendations on another good catheter? Thanks in advance.
