@gator1965 If your pain has been going on for that long I would definitely get a second opinion from the best possible orthopedic surgeon you can find.
I have had two knee replacements and never experienced anything like that. There are a couple of private groups on Facebook that are just for people with knee replacements. That can be a good source of information also because most of the people who are part of the group are there due to problems. It can't hurt to check as many resources as you can find. There really is no monitoring of those groups though as there is on Mayo Connect.
I hope you can find some answers and are able to get some help in alleviating the pain. As I said up top, the first thing I would do is get a second opinion.
