I had a complex hip replacement at the end of January. I had soft bones and I now have a cable and a screw showing up on my hip x-rays. I had to use a walker for the first six weeks and then afterwards I found it too painful to walk so I ordered a cane from Amazon and I used that for another six weeks. I have only started to walk normally after almost 4 month post op. Who told you that you should feel hunky dory after only six days? I do recall meeting a few people in the past year or two who said that right after surgery they were able to walk right up the stairs. Well, yay for them. This is considered major surgery and everyone will have different outcomes. My thigh still hurts on occasion as does my knee but I am so grateful that I do not wake up every night in pain like I used to. I no longer obsess about chronic pain and if this is as good as it gets for me, then I am OK with that. You need to give it time. Three days after surgery it took me 22 minutes round trip to get out of bed and make it to the bathroom which was less than 15 feet away. If your x-rays are good then you are most likely going to get OK. All my x-rays have been good for the past 5 months. My surgeon told me that it would take 18-24 months before I am fully recovered.
