Yes, I did have swelling under my eye. It went away a few days after surgery and then returned a couple of weeks later.  Mine didn't go away during the day, but only lasted 3 or 4 days and then went away and hasn't returned.  My surgery was July 27th and my post surgery symptoms are almost all gone.  For the first few weeks I had random numbness in different fingers on my right hand (I had Left side surgery) and some trouble with speech.  I have not had any symptoms for almost a week. I think I have done better when I make sure I drink plenty of fluids and don't overdo it.
