Extreme Wrist Pain

I have had this terrible, really bad wrist pain for a few years now.  It is located on the top of my wrist right in the center and when the pain is in full swing I cannot fully bend my wrist either up or down without terrible pain.  I have not injured it to my knowledge.  I have had 3 doctors look at it, I had a negative nerve conduction test, and nobody seems to think anything is wrong with my MRI's or X-Rays.  It hurts to put pressure on it, I think that is what triggers it most of the time, for instance if I were to do a push up right now, the pain would be terrible right afterwards and for days/weeks.  I am crying in pain and I have no idea what to do, it is not carpal tunnel, splints nor any anti-inflammatory works, and I am tired of hearing that from every single doctor I see.  I am desperate for help, if anyone knows what I should do please let me know :(
