Chronic knee pain
Brother is having knee pain since one and half years. Have consulted couple of doctors since then but no diagnosis of anything found. Recently he had undergone a full body tests. In results eosinophils absolute count was found 1.87×10^3. Platelet is also high and Rbc is low. Due to the pain he is unable to run properly or play sports. Even benting of knee is causing pain. Could there be any particular diagnosis method to figure out the problem.
