Arthritis

"Without this oil from my internal lubricating system, my joints will seem positively arthritic!"

- C-3PO, as he sprays oil in the face of a possessed Chewbacca

Arthritis was a condition that affected joint movement, often causing discomfort. After an entity known as the Darker had manipulated Chewbacca's emotions and turned the Wookiee against C-3PO, the protocol droid sprayed oil from his internal lubrication system in Chewbacca's face. Threepio claimed that without the oil lubricating his joints, that they would feel arthritic.
