you need to get her checked by a good ent, it probably isnt serious, but there are really serious possibilites in the area. my son had a cholesteatoma,,, google it if you want, scary, thank goodness my pediatrician saw it. we went to 3 of the best ents around, none of them could believe that my ped saw it. he got it removed and tg he is ok, but its potentially really serious. just saying. even a regular ear infection can become brutal. i had one so bad that wouldnt go away, as an adult. and i ended up crying, in pain, on 5 different meds, steroids, had a reaction to one of the meds and got this crazy rash all over, and the whole thing lasted so long. and i couldnt hear on that side for months. and it really really hurts so much. so... i would def get her seen soon if it doesnt go away ... good luck
