Not bad, considering I got this done this afternoon. I've experienced far less discomfort than I expected to--typing without a problem. Which is good, I've got a LOT of work to do this week!
It was mostly painless--there were just a few places where the artist touched a nerve (kinda unavoidable), but all in all, I was mostly just left with a weird 'buzzy' feeling in my hand (go figure) and a little stinging for a while. I came home and took a nap (still fighting this stupid cold) and woke up with no swelling of which to speak and no real pain.
Now... let's see how much touch up it needs in a week or two. Palms are notorioiusly stubborn when it comes to holding ink.
