Even before treatment for ReA my Sed rate was in the normal range. I did not have a CRP done until much later. CRP wasn't used back then.
As you may know Reactive Arthritis (ReA)and Rheumatoid Arthritis (RA) are very different. ReA is a TH2 whereas RA is a TH1 disease. Still they share many similarities. I'm sure we will discuss those in the future. Both on this forum and perhaps others when appropriate.
