Ds3 (aged 9) had grommets put in 16 months ago. Since yesterday he has had an earache and some dried blood in one ear. I've given him calpol twice when he has needed it and he has been playing etc as normal. I'm wondering if his grommets are about to fall out or maybe a mild ear infection. I'm reluctant to take him to the gp with everything that's going on with covid 19
