Lumps Above Lip After Filler Injected Months Ago; Scar Tissue? Can It Be Fixed?

 I have a lump on each side of my top lip..the one on the left is VERY visible & ugly. I had Juvederm for the first time several months ago. I didn't care for the look, so I never got it again. In the meantime, I have these lumps on each side that I am afraid are scar tissue. After seeing a dermatologist, I was told that the only way to fix the problem is by making a small incision to remove. The Dr. that did the procedure, however, said that hyaluronidase would remove it. Aside from a lump above my lip after filler done nearly a year ago, I also have an obvious crooked smile now on the same side as the lump. Is it possible that the lump is scar tissue or if the crooked is related to the Juvederm? Can anything be done for either one?
