"Does anyone know of any exercises or methods of controlling this pain?"
Your best bet is to get your orthopedic surgeon to refer you to a good physical therapy program. A really good physical therapist knows this stuff pretty good.
Years ago, I had knee surgery. After I got out of the hard cast, it was not getting better, so I asked the surgeon about PT. He said, "Sure, we have a knee program here. Do you want to do it twice per week or three times per week?"
I replied, "How about both?" So, I started doing PT formally five times per week, and informally more, to the tune of about three hours per day average. It's tough, but that works. If you don't get it halfway cleared up now, it might haunt you for the rest of your days.
