My 9yo currently has chicken pox, he's covered in them, has had a high temp since Tuesday night that is only controlled by calpol, and has had tummy ache /nausea since then...but today his throat has really started bothering him. I had looked 3 times today and can only see slight redness but he's woken him up again just now and he's clearly in a lot of pain. I've given him (more) icecream and he's drinking his water. Just hoping for any suggestions/ideas?
