Luke has been limping for over a month now. He doesn't do it all the time, but he does it enough that people have noticed and commented on it. His normal walk is a little funny I guess, but then occasionally he will start noticeably limping. I can't recall him ever getting hurt and he does not seem to be in any pain. He will walk for over a mile (seriously - Charlie takes the boys on walks in the evening sometimes and Luke refuses to ride in the stroller, opting to walk for 1.3 miles instead). Anyway we figured since it's not going away we should have the doctor check up on him. Unfortunately I left the appointment feeling more worried, not less. They took some x-rays and could not see any sign of injury or anything in the leg. The more concerning point is the hip which will have to be x-rayed further and studied by a radiologist. If you google "limping toddler" you can read all about the horrible diagnosis that are possible. I'm trying not to get too worried yet until we know more.
