I had that a little bit too, but that's pretty normal for me - when the rest of me is achy, I still get an ache where my leg was broken 30 years ago. I don't know the science behind it, but I think the deal is that your body never heals entirely from anything like that. It's always going to be a little different from the surrounding bone/ligaments/muscle, and it feels normal most of the time, but when you're run down, you can feel it.
Maybe the immune system reactivates very easily at the site of an old injury, on the general principle that if you were hurt there once, maybe it should pay special attention to that area in the future? (I'm just guessing, though.)
