Without examine to child its difficult to say that , whether it is major or minor injury
I hope so, it should be minor,
I would advice:
It needed proper diagnosis with investigation.
X-Ray- Right shoulder with clavicle
Restriction to movement of right shoulder. Because condition might be worsen.
or apply any ointment.
For temporary you can give Analgesic/Painkiller.
You should get her evaluated once for her complaint to get her examined physically by a pediatrician
I wish our baby get well soon.
