Hi Helenefm. You certainly appear to be one of the lucky ones in your recovery! Good for you! I only wore my TEDs for 2 weeks. As long as you're up and about a tiny bit every few hours, you don't really need to worry about the blood clots (or so my OS said). I am almost 6 months out and I just now have been able to stop all pain meds aside from Tylenol. I can't believe you're not feeling pain so shortly after. I'm totally jealous! I started driving @3 weeks, but only to PT and back and I would never last more than an hour or so. The 1st time I actually 'went out' to do anything other than PT or to the store was 6 weeks out and that was a big deal for me. ;-) I was till using crutches at that point and traveled with ice packs everywhere! I used my walker for about 3 weeks, and longer only at home, especially in the mornings, before progressing to a cane which I sadly had to use for a couple of months. The rule of thumb is to not move on to a lesser device until you can walk 'properly' with no limp using the current device. Meaning, until you can walk 'heal - toe' using the walker without a limp, don't downgrade to a cane.
I've had one of the tougher/longer recoveries, but I'm getting there. Please be sure not to overdo it. Even though you're not feeling much pain and aren't tired during the day now, you have just been through a hugely traumatic surgery that your body needs time to heal from....
