Good evening @lane. Welcome to Mayo Connect. Whizzing through my emails I came across your message and wanted to give you a reaction from somebody who is not a medical professional:

If there is infection deep in the hip joint after surgery, it might not "appear infected," even though it might be. If I were you, I'd check my temperature every few hours, and if it rises a couple of degrees or more, I'd have somebody take me to the emergency room. Whoever takes you there will be an extra set of ears to hear and remember what the ER medical staff tells you.
