Lump on lip after Juvederm 9 months ago (Photo)

I have had juvederm injections numerous times in the past and have never had any problems.About 10 months ago I had the juvederm injections in my lips and i noticed a small squidgy lump appear.i assumed it was swelling but after a few weeks had passed it was still there.it feels as soft as it always has been however the lip area itself seems raised and puffy.i have contacted the doctor who did the injection but she seems reluctant to try hyaluronidase however I don't see what other option I have
