I have a three year old son, has fever was low grade 98-99, now its 102.2, was told yesterday that he has transient synovitis of the hip. He was diagnosed with an Xray only. I am curious if this would be the normal for a diagnosis of this illness. I would think there would be a CBC or WBC included, possibly an MRI, or even urine test but none of these were done. Is there a possibility that this could be septic hip even without excruciating pain, or some other diagnosis?
