Hard lump at corner of eye after upper blepharoplasty

I had an upper bleparoplasty done 11 weeks ago and had complications. My right eye drooped in 6 weeks and I already had revision surgery to correct it. I now have one big eye and one little eye.

To top it off, I have a hard red bump on the corner of my left eye. My Dr (a well known Oculoplastic surgeon in Austin) said to massage it and it would go away. Well, its quite sore from massaging it (for weeks) and its not going away. What is it and what can I do about it?
