Hello and welcome to HCM.
Thank you for your query.
Firstly, please do not discontinue the antibiotics, as this is the only reason why your daughter's ear infection
is under control, and will hopefully be completely cured soon.
Not all symptoms need to belong to the same condition. There could be another underlying problem.
Also, from your write up, I am not sure whether the leg pain was present even before she started on the antibiotics, if so, it is a clear indication that the leg pain has another cause, and is not a side-effect of the antibiotics.
If she is walking on her toes, and this does not trouble her, then there could be a possibility of some injury
to the heel of her feet.
Where exactly does her pain exist?
You could get this checked with the help of an x-ray of her foot.
I hope I have succeeded in answering your questions, you could write back to me anytime for further clarifications.
