Jak...you poor thing. You have really done way, way more than you should have at this early stage of your recovery. Believe it or not, you ARE still early in a recovery that can take many months before you really start to feel normal again. You've earned your Gold Star. Now you must go a different route or you really risk delaying your eventual recovery and possible even risk getting chronic pain problems. Please don't allow that to happen!
Put yourself first from now on. That means for at least two weeks, no chores around the house (other than maybe preparing yourself small meals) and no running errands. No meals out or extra walking. Use your two crutches if you are at all limping. Employ lots of icing, elevating and resting mixed in with a walk around your house from room to room every hour or so. If you start feeling better, congratulate yourself for doing the right thing, but don't take that as a signal you can increase your activity until the two weeks is over. Your hip needs some serious recoup time.
You know the pain you mentioned that is bothering your mother 3 years out from her hip replacement? This is the type of thing that comes from too much activity before your hip is ready. I'm guessing your mom is a "go-getter" just like you are! Remember that all this is just temporary. The goal is to have you forgetting you ever had a hip replacement as soon as possible. But you must start thinking of your recovery in terms of months and not just weeks.
