I have been told I have very little fluid....however still at 16 months have soreness and stiffness. Not nerve issues, no vascular issues and getting a bone scan Monday to show if there is inflammation. My surgeon basically told me the same thing....some people just have pain, soreness and stiffness and have to live with it. I went and got a second opinion. The surgeon may have done a great job with the actual replacement but nothing after. I"m still hoping for a answer...I hope you find out what is causing the fluid to build up like that because that is not normal after a replacement. Praying you find some relief.
