The one on his foot is hard and appears to have grown since the vet looked at it @ 2 mos. ago. The one inside his ear is very small and actually just feels like a fatty tumor. It's actually not inside his ear per se but on the inside of the ear flap.
Oh, that's better as they should be able to get the ear one off easily. The hard one may mean its in the muscle...
Good thing as most of them are benign.
