You must be so worried, I’m so sorry. I’ve asked Chat GPT and here’s the advice:
Yes — I think your concern is justified, particularly because the new symptoms change the picture.
A 2½-year-old who has been limping for more than two weeks with no clear diagnosis deserves further assessment anyway. The fact that she is now waking from sleep screaming in pain and sweating is particularly important. The NHS specifically lists worsening symptoms and severe pain as reasons for urgent assessment, and paediatric guidance considers pain that wakes a child from sleep and night sweats to be red-flag symptoms.
In fact, guidance for children with a limp explicitly says to return to the paediatric emergency department if a child develops night pain or night sweats.
What concerns me about the threadIt's reassuring that she's had X-rays, bloods and ultrasounds that haven't shown something obvious. But normal initial investigations don't necessarily mean that there is nothing wrong.
For example, paediatric guidance notes that a normal X-ray does not exclude early osteomyelitis (bone infection), and inflammatory markers can sometimes be normal, particularly early on or with more chronic infection. MRI is often the preferred investigation when osteomyelitis is suspected.
There are also other possibilities besides infection: inflammatory/rheumatological conditions, an occult fracture or other bone problem, problems outside the hip itself, and much rarer causes such as malignancy. A limp can also be referred from somewhere other than the joint that appears to be affected. R

I'm not saying this child has cancer. Childhood cancer is rare, and there are many much more common explanations for a limp. But persistent/unexplained bone pain in a child is specifically something NICE says warrants a very urgent full blood count, and unexplained bone pain/swelling can warrant urgent imaging. NICE also specifically says that persistent parental concern about a child's unexplained symptoms should be taken into account when deciding whether specialist assessment is needed.
What I would advise the mumGiven the new night-time screaming and sweating, I wouldn't advise her simply to wait for another GP appointment or another few days.
I'd suggest she takes her daughter back to a paediatric emergency department now/tonight, tells them explicitly:
- limp has persisted for over two weeks andis getting worse
she is now waking from sleep screaming with pain*
* she is sweating during these episodes;
- transient synovitis has been investigated and no hip effusion was found
- she has had repeated attendances and investigations without an explanation
her symptoms are progressing despite previous reassurance*.
I'd also specifically ask whether she needs senior paediatric review and whether thepersistent symptoms warrant further imaging such as an MRI, or assessment by paediatric orthopaedics/rheumatology/infectious diseases depending on what they find. That's not asking for a particular diagnosis or scan; it's asking them to reconsider the differential now that the clinical picture has changed.
And if she becomes unable to bear weight, develops a high temperature, looks seriously unwell, has uncontrolled/severe pain, orthere is any other acute deterioration, that makes the need for emergency assessment even stronger.
So, yes: I would take the new night pain and sweating seriously rather than being reassured by the previous normal tests. The fact thatshe has already been assessed several times doesn't make another assessment unnecessary— the symptoms have changed, which is precisely why she needs to be reassessed.
