These problem can be associated with the condition of the ear, which is present as congestion. This congestion can lead to headache and other things which you are describing regarding your daughter.
When there is some irritation in the ear it can cause the problem of nausea
, headache. Other thing like very low heart rate
can be there because of the vagal stimulation which can decrase the heart rate. Tingling sensation
can be just feeling which may be because of the problems associate.
The medication given for the ear condition look ok and if the congestion is more and is not reliveing with these medication than have consultatin with ENT doctor regardign this condition.
Thanks and take care.
