Sorry posting for traffic.
Over the past week everyone in the family has been unwell somehow. Youngest DS with an ear infection. Me with a bad cold, DP with cold etc.
Today DS1 who is 4 was sat on the sofa watching a movie and every few mins he'd make a little moan/whimper I went to check and he's eyes were all teary and he is saying his whole throat hurts whilst grabbing the circumference of his neck.
Nothing else seems to be wrong, he has eaten well, no temp, I looked in his mouth and seems to be no irritation (I was worried about strep throat).
He just wants me to lay with him and watch TV and seems sad. He's not usually that much of a crier so I'm trying to figure out what's causing this/what he could be coming down with.
I've gone into overdrive in my mind and had a little feel of his neck and there seems to be a little round lump that moves around when I wiggle my finger on it and I don't think I've ever felt it before and I can't figure out what it is. It's on his side near collar.
At the moment he's had Calpol and seems a bit better but I'm a bit worried. 
Any insight?
