Limping getting worse, what could be causing it. Perthes?
First a bit of back story, back in September DS started limping one evening after a busy day on an inflatable obstacle course. The next morning when he woke up he could not bear weight on his leg at all so off to A&E we went.
It didn't appear to be an injury, and the docs thought it may be a result of an infection. However as a precaution they got him back a week later for a X ray to rule out perthes disease.
The X ray seemed clear, so even though the hip was taking longer to clear than had been though it was improved and so was assumed to be irritable hip. We left with instructions to return to our GP if the problem continued.
While it did take quite a while for things to improve he was OK for a while, but has still complained here and there.
When the complaints increased, and we could see him limping we went back to the GP and have been referred back to the hospital.
However he's now getting much much worse, limping pretty much all the time. He has to sit out of PE at times and I've recently had to carry him home from school as he's not been able to walk that far. A few weeks back we took him to a playground and he was able to climb the equipment, this week he was really struggling.
Evenings are getting bad and it's keeping him awake at night 4 or 5 times a week now, especially after a busy day.
It's still just over a month till his hospital appointment and it's hard to watch him getting worse like this.
I'm wondering if even though Perthes was ruled out a few months ago it could still be that. Does anyone have any experience of it?
What else could be causing him to limp and how can I persuade a very lively 7 year old who's also got Autism and sensory processing issues to take it easy?
