You've seen just about every kind of doctor except the right one!
msnova is correct, you need to be evaluated by a rheumatologist. I find it a bit strange that the other doctors have not referred you to one.
The first thing your rheumo is going to do is diagnose the EXACT type of arthritis you have. There are three types of arthritis and depending on which type you have, that will determine the treatment.
There are incredible new drugs out there for arthritis, but some of them carry pretty scary warnings, so be sure to discuss the pros and cons in great detail with your doctor.
You absolutely do not have to suffer daily, chronic pain any longer. Find a good rheumatologist and get your life back!

I would suggest a rheumatologist. What you are describing sounds like something more than garden variety arthritis.
