Lower blepharoplasty prolonged swelling. Is there anything that can help? (Photo)

I had a lower blepharoplasty done almost 6 month ago, I developed a hardened area about black pepper size after 2 weeks inner corner of right eye which my doctor treated with little steroid injection and it helped but it's didn't go away completely. I also have prolonged swelling below underage area which is not going away. My doctor said it'll slowly go away with time. Is there anything that can help ?
