I just recently noticed my BTS to have a rather puffy front leg. He doesn't struggle to walk on it or anything, but it looks quite abnormal and he never had it before.
Here is a picture (sorry for blurriness) first image is his good leg, second is the puffy one.

I have booked a vet appointment to be safe, but I figured I'd ask here if any of you have seen anything like this before.
Thoughts?
