Glad to hear the holding is going better now!
I find it helps to do whatever foot is most available and if the foot pulls away, move to a different foot and get back to that one later, and if the piggy is getting really antsy, the nail clip may turn into a two session job. I always give out treats with nail clipping sessions to make sure it's a happy thing in the end ... food can also work nicely as a distraction, so the piggy will let you do more in a sitting ...
I've had piggies who are pretty relaxed with me handling their paws and others who hate it, even when I'm not actually clipping ... the relaxed ones are usually the exception. As Piggies&buns stated, some piggies are quite dramatic even when nothing is wrong and will scream or react when not actually hurt ...
We have a dog that used to be the same way, she'd complain even if you made a brushing motion, whether you were touching her or not (she did finally get over that).
