Weird bumps after lip filler, are these scars? (Photos)

I had lip filler done as always on my upper lip but this time we put the rest of the syringe in my cheeks so we may have used a thicker filler. I noticed the next day that I got these lumps where the injection site was and just waited for them to go away. After 3 weeks and massage they still did not budge. My practitioner tried poking the bump and popping the filler out and then a week after tried dissolving the bump it self with small amount of dissolved and still nothing. Are these scars???
