lots of questions sorry
i also had a cath. no big deal. they put it in when i was under and it came out the next day. it was annoying walking the first couple of times with it in. was happy when it came out. couldn't feel it in there though and could hardly feel them take it out. the drain was funky feeling when they took that out. didn't hurt. just felt weird as i could feel it move under my skin. where you're having the lap band you may not need a drain. i bet you still have the cath and lovenox injections. don't stress over this stuff. it's minor.
