I'm working to address his pain first. It's difficult as a single person to handle the feet and treat at the same time, maybe put some PB in the muzzle while I'm back there? When he is getting his nails trimmed and his cold laser treatment, I hold him in place and he doesn't move, lift a lip, snarl, whatever, so I think that eventually he may associate that with good things.
Anyhow, he did do some roaching this evening, which means he is feeling better.
