Hi!
As Benji once told me: "Soreness is fine, in the beginning. Pain, is not, ever". This to say that if your hand hurts you must stop and take the pain seriously. We don't want to end up with and injury.
It could be that you are locking the wrist too hard. Sometimes I catch myself keeping the hand rigid as If I'm a statue and I have to stop and loose it up a bit. Also try to not keep the fineliner in a death grip - which is another common issue.
And finally it may be that your hand just needs time to adapt to a new position. Give your joints enough time to rest and take a break whenever you experience any soreness.
