This was brought up to me from an online acquaintance and I've seen it mentioned here a couple times. Is one leg being shorter than the other a common thing? Do I bring this up to my surgeon (follow-up on September 3rd) or my GP (VA hospital, had no involvement in my knee replacement other than to string me along for three painful years before giving me authorization to see the off-site doctor- I have my yearly check-up on August 13th). When I do walk (like those two times I've walked a mile), I get tired, but not on the surgical leg. Usually its my hip in the other leg. When I was pregnant with my third child (16 years ago), she pinched my sciatic nerve and it caused me some lower back and right-side hip discomfort. Fast-forward a year later, I was in a rather bad car accident. The chiropractor I ended up seeing (three times a week for several months) fixed an alignment issue that took care of that problem. I rarely had a problem with that hip or my lower back. But, now it seems to be happening more often. That's when the "one leg shorter" thing was mentioned.
