Are these knees swollen??

[MrsMuddlePluck]

My physio keeps saying they are but I can't see it? Maybe I've just got so used to it I've forgotten what a normal knee looks like?!

They look better than mine. I had an accident with the dog recently, went to the doctor who looked at my injured left knee and declared it to be very swollen. She then compared it to my right knee and decided it was probably ok. Not much help, sorry!
