Revisions for me were pretty easy except for a bleeder that caused a hematoma. That went away after a few weeks of Ice. All was great until the hip revision got infected. I have no pain, no fever, no dislocation, no fluid, no signs of infection by x-ray or bone scan but started as a large bump under the anterior scar that has now become a perfectly round oozing sore about the size of an eraser on a pencil that won't heal.
