Should lip filler feel lumpy?

Swelling and some lumpiness is normal for a few days up to a week or two after injection of filler into the lips.

How bad do lip fillers hurt?

As the anaesthetic is not being injected into the desired areas, but rather being absorbed through the pores, although it is pain-free, you can feel some discomfort. Apart from that, the procedure is the same as if you were getting it with an anaesthetic injection.
