What causes sudden intense hip pain in a child?
Morphine or pethidine should be the mainstay of treatment.
Thanks for asking on HealthcareMagic.
I have gone carefully through the query and understand your concerns. Sicne MRI or CT scan does not reveal anything conclusive, bone tumors and other similar causes can perhaps be ruled out. There are two broad possibilities to consider. The most likely cause is some sort of muscle spasm although it is hard to comment definitively without clinical examination. Hot compress and muscle relaxants should be given along with the current line of pain medication. I understand that the response is inadequate but all that can be done is to see which medicine ultimately provides relief. Although addiction forming on long term, on short term morphine or pethidine are very safe and should be the mainstay of treatment. The nausea can be a side effect of such medication and antiemetics should provide relief.
The possibility that needs to be ruled out is some inflammatory cause. In that case the CRP (c-reactive protein) or the ESR would be raised. If this has not been checked, please get it done. Negative results will rule out inflammatory cause.
