Apologies mods if this isn't the correct place for this post...

DS seems to have a slight limp since waking this morning. To me it looks like when you've been sitting on your leg wrong and stand up with pins and needles and your legs kind of buckle a little and are a little stiff for a minute or two. Except that it's still happening now. He doesn't seem to be in any pain, there are no obvious marks on him anywhere and he's had no falls/accidents of late that could account for the limp (that I know of). He's definitely favouring one leg though, and it was worse again after his lunch time nap.

Just wondering if anyone has ever had this happen to their toddler/child, or have ever heard of such a thing? A quick google search suggests it could be a transient thing, or could be a bone tumour or leukaemia...!!!

Any help appreciated!
