Went to Orthopedist due to trouble with replaced knee said sedimentation and inflammation levels are hig Sed rate 38. But said I did not have an infection.He also said white count was up a little.But my knees hurt .What does the Sed rate have to do with all this and should I be concerned.When I asked about the Sed rate and I flammation and white cell count he said he was a surgeon a d did not practice that kind of medicine. I have no choice about going to him
