My two year old, who usually is a very good sleeper, started having really unsettled nights a few days ago. Literally screaming and screaming for hours but I wasn't sure what the problem was. He's been co sleeping with me since which he doesn't usually do.
Then two days ago his throat started sounding a bit croaky and now he's completely lost his voice so it seems a sore throat is to blame. I've been giving Calpol and ibuprofen but it doesn't seem to be doing much he basically only sleeps at night through pure exhaustion after screaming in my arms for hours. He has spells during the day where he seems okay and happy but he's definitely grumpier/ clingier / not wanting to eat anything apart from little bits of fruit.
I wasn't worried and assumed it would clear up by itself in a few days after lots of TLC etc.. but he's just been crying and it seems there are now sores on his tongue and roof of his mouth 
Is this normal for a sore throat in a toddler or should I be taking him to someone? I feel so bad for him and don't know how to help.
He gets a bit warm to touch at night but no official temp so far fwiw.
