4 weeks post op fat transfer to tear trough; still in pain and feeling tightness?

Hi, today is exactly 4 weeks post op.Lower eyelids still hurt and feel the hardness/tightness when blinking the eyes or when the eye muscles (love bands) move at any facial expressions. My puffy dark circles have become 2 big round puffy panda eyes now. I am disappointed with the much lower and prominent tear trough lines. I am already thinking of doing lower blepharoplasty to remove those fat. How soon can i do it? Thanks in advance!
