just had a flex sig in may. it was SUPER quick! like under 5 minutes, not bad at all. yes some pressure and feeling weird and all but to me its worth it because i want to know whats going on up there!
i also had a problem with leaking, but mine was a reddish brown mucuos blobby type thing. i wore pads for like a year. no explanantion for my leaking, it was just part of the flare. i had a stubborn isolated spot in my sigmoid that was refusing to heal.
the flex sig will be quick and over with before you know it, i promise!
