Ds has said for a while ( about a year) that he gets rocks in his mouth. I've never seen one so just thought it was a bit of snot coming out of his throat.
At the weekend his breath was seriously revolting, made me feel physically sick!
Yesterday he said he'd coughed up a rock at school, then again later. There was nothing to see as he said they slipped through his hands 
Last night he was running a temp & said his head & throat hurt.
This morning he went to be sick & coughed up a vile smelling lump (which i bagged up!) , checked his throat & it was swollen on one side.
Managed to get him a doc appointment
& seems he has tonsil stones & tonsillitis.
Does anyone have any experience if this? Googling it it can get pretty grim & is unusual in kids , so I'm guessing it'll get worse as he gets older.
Dr said if it persists he'll refr to ENT
