Thanks for posting,
From your description it is very possible that your daughter is having acute gout attacks (if gout runs in the family then the probability is more likely). If that be the case, then she will require specific antigouts medications such as allopurinol
to treat the gout.
Another possibility is polyarthritis
(septic) which will require treatment with antibiotics and NSAID or SAID.
is possible but very unlikely given the scenario. Other causes such as multiple cellulitis
might be considered but very very rare as presentation is very very atypical.
You will need her to consult a doctor as soon as you can go to the hospital so that she can properly be examined and appropriate treatment given.
Hope this helps
