Hello, my son is 5. This evening at tea time he said he could not eat because his throat is hurting so before bed I gave him calpol, he's not settled really all night he keeps on crying every few minutes, hes burning up I don't have a thermometer to check his temperature but he's definatley hot to touch, even with the fan on his back and tummy are warm. I thought his heart seemed to be racing so I did a pulse check and it was 122 BPM, does that sound worrying? I don't have a clue what his heart rate should be and Google gives various answers, any advice much appreciated thank you
