Is this fat necrosis or a hematoma 18 days post op? (breast reduction 32DDD to 32 B/C) (Photo)

During the first week, I had only yellow bruising. During the start of the 2nd week, on the left, I started to feel more swollen,and had a dark bruise. On my appt. 2 weeks in, surgeon just yanked all of the tape off no adhesive remover and left me more swollen and worse purple bruising around left areola. Took off silicone sheeting when I got home,not been wearing it since and have been oozing, but now 4 days later, bruising has gone away a bit, and I have a purple hard spot on top of breast.
