Well... maybe I need to drop back on Ben's pain meds. I was warned it may cause him to be "zombie-like". He his pain free but when he walks he is dragging his toes, particularly his front left. I'll cut out his mid-day dose and drop the night dose to half.
Keep a close eye on things. Hopefully the nerve impingement is not increasing. Knuckling under of toes can be indicative of increasing problems. Seriously hoping this is not the case.

I think I'd call the vet and tell him/her about this.
