An ear infection can definitely cause him to lose his balance, become afraid to jump up on things. Especially if it's a bad infection.
Give his ears a thorough cleaning, and keep using the meds. Hopefully the meds will kick in soon and he'll be back to normal. If he's still not doing better after 5 days, I'd go back to the vet and ask him to check again, or get a second opinion.
How old is Kugle? Is he tilting his head?
