Is it normal for lip fillers to feel hard in your lips?

2 weeks ago I had 0.3 injected into my upper and lower lip to try and fill out the lips from previous filler. But now they're so hard to touch and feel extremely unnatural, and they throb a little after rolling them? When I grab my lips they feel like cylinders, but they don't look swollen at all and the woman I get them done at is extremely well known and I experienced minimal bruising. Would injecting a small amount of hyaluronidase be able to soften them?
