Yesterday my DD (11) showed me a lump underneath her ear just at the top of her jawbone. She said it had been there a while (but no idea how long) but it started hurting yesterday so she told her teacher. I got home expecting to find a pea shaped lump showing that she had a swollen lymph node. It's more like the size of a grape 
So I took her to the GP this morning and saw a nurse practioner who said it's probably the result of an infection though she couldn't find any signs of one and DD hasn't been ill. She said to come back if it's still there in 3 weeks because they're not going to do anything about a lump that's been there for one day!!
It looked like it had got bigger overnight and I've just got home from worked and checked again. It's got bigger again and there is a second pea shaped lump behind that one. AIBU to think that 3 weeks is too long to wait and see what happens?
