Pulsating bump where Juvederm was injected on inner lower lip. Doesn't hurt, should I be concerned about labial artery? (photos)

I received lip injections about a month ago. This spot doesn't hurt, but when I look this spot/nodule in the mirror it's almost clear as if I can see the filler itself, it's raised, and it's pulsating as if it's right on or near an artery. The fact that it's pulsating and looks like it's near an artery is alarming to me. I went to what I thought was a reputable injection RN at a plastic surgeons office. Should I be concerned about this?
