So I had my knee replacement 13 weeks ago today. Pulling my stitches out accidentally after the first week did not help, but my recovery has been pretty slow. The knee block they give you during surgery did not work much and I had to stay an extra day in the hospital because they could not get my pain under control. I have been in pain every day since...even with pain meds. My mobility is great but going from sitting to standing is hell. And now overnight I have build some fluid on the knee. My advise...don't check the Internet for symptoms, it will only freak you out. I called my doctor and since I have an appointment in a couple of days they said not to worry. But I still worry. Most days I wish I never had this done. Has anyone had an infection and if so what were your symptoms?
