Why do I still have discomfort, stiffness and limited range of motion 2.5 months after Juvederm lip filler?

Had 1ml of Juvederm injected into lips (mostly bottom lip) using a cannula. Experienced significant swelling and stiffness for over a week. Doctor injected hyaluronidase into area where filler was too close to surface. However, I still cannot fully purse my lips without discomfort. I can feel areas of hardness when I awkwardly attempt to purse lips to distribute lipstick. Is a difference in texture/range of motion normal? Will I have to wait until the filler dissolves to feel "normal" again?
