我头上的伤口已经愈合了。

The wound on my head has healed up.

几天前我的手臂被不小心划伤了，不过伤口还是像往常一样很快的愈合了。

A few days ago, I accidently cut my arm, and that cut appears to be healing normally as well.

当它们愈合的时候，我种感觉不好——因此，我不会‘清洗它们’，而是再次隔开伤口。

I felt kind of bad when they started to heal - and so I would 'freshen them up' by cutting again.
