Took dd(5) to dr yesterday with earache and temperature following her getting a cold virus last week with bad cough . She'd had ab's for an ear infection 2 months ago but saw a different dr this time. He thinks she is developing glue ear as her timpanic membrane on one side is bulging from the pressure of fluid behind , although not currently infected, and the other also has some fluid, so we have been given lots of advice of preventative measures to try to decongest and drain it off before it gets serious enough to require grommets. Apparently she almost certainly can't be hearing properly and probably not since her previous infection Might explain her recent grumpiness too.
tbh I'm shocked that she has developed this at the age of 5, having only had 2 or 3 previous ear problems, the only thing I can think of is that we always kept her bed head raised for reflux until last year, as now we've been advised to do for this.
