Smell remaining after washing one's hands

Q: I was having a shower and was washing my backside from faeces. I used soap to remove the smell. I then smelt to check the tips of my fingers to check if the smell had been washed off and it had. After I had oiled and dried my body I after an hour or so passed my hand over my nose and smelt something like faeces on my palm. I only checked my fingertips when I had cleaned myself, so I am guessing that it had not been washed properly. I am now worried I have made my whole body and clothes impure.

Doubts

Q: I had a small cut on my finger. There was a little bit of water in the wound but it was not flowing, it was still within the wound. I wiped some cream on the wound and then creamed my body. At the time of wiping I was under the impression that the wound had heeled, but after the cream had dried I noticed there was still water within the wound. Did I spread any najis?
