Upon further investigation - reading & research - last night on the internet, I REALIZED (duh) that his twitching was from his skin allergy. He is having a flareup - which the vet & I discussed him having. His itchy skin is making him dig & twitch & be uncomfortable.

So I gave him a pred ... the dosage is Every 2 days or as needed for flareups, so I guess this is a flareup. I guess until this is over, I will give him one every day as he acts like this. But I'm still gonna call the vet monday morning to confirm that I'm doing this right. Poor guy. He's just itchy!
