My toddler is 23 months old. In March he had irritable hip. He couldn't weight bare they did a hip X-ray said he was constipated. Took blood and said he had high inflammation and diagnosed irritable hip. Since then my toddler hasn't walked properly. He has a very noticeable weakness on his left side. His knee gives way daily. I took him back to the GP who referred us for physio back in may we still have no appointment for this. The past four weeks he has been waking up crying touching his leg saying ouch. The crying lasts between 1-3 hours until he eventually settles. Should I take him back to the GP or wait for the referral to physiotherapy?
