6 months after facial feminization, soft swollen lump still present in chin. What are my options? (photos)

Hi, I had ffs surgery turning 6 months now. I had a coronal brow lift and chin shave. However, my doctor said that through this technique, he could move my muscles and fat, so he would remove the fat from my jaw to make it more feminine. When I woke up, I noticed that the suture inside my mouth (from the chin) was a little open, but my surgeon didn't care about that. After 6 months, I have a soft lump in my chin that doesn't go away even with lymphatic drainage. What I can do?
