Is it normal to have clear fluid pockets on the inside of lip months after Juvederm? (photo)

It's been over 8 months at least since I've had juvaderm ( just a thin line in top of upper lip and I have always had these little clear pockets of fluid on the inside of my lip where the injection was no where near. Usually I forget they are there and it ads some extra fullness to my lip but today they feel larger for some reason. How do they form there if is nowhere near where I was injected and is it safe to leave. They have never been sores or open areas at all just filled with clear fluid.
