I recently started using the Nicoderm CQ patch and I've been placing them on my belly. Someone said that it can leave marks, so I decided to place them where I know I will not be exposing.
I was told by a friend that I'm supposed to place it on my upper arm, as long as it's above my heart. A website mentioned it has to be on the upper arm or trunk--what's a trunk? Also, why doesn't the guide book that comes with the patch mention that? It says that you can place it anywhere with no hair and no cuts. Can I still continue to place it on my belly?
