Also, if you have yarn overs next to the decrease, it depends on which side of the decrease it is, and what decrease it is. This can open up or close the hole.
Normally I would say you should go on, making the ssk from now on. If you're not too far into it. And even then,... I think I wouldn't rip it.
The ways of Yarn are inscrutable.
