He's 5, had all his jabs. I've probably left this way too long, but for a couple of years now he's been prone to getting what look like bites on his arms and shoulders. Just three or four, they occur in the same place he had his MMR (coincidence?) and on his shoulder and other arm. Sometimes he'll get the odd one on his back and belly too, but his shoulders and arms seem to be the common places.
It comes up as a red lump with a little dot in the centre that I presumed was the actual bite area.
He'll get them every 3 months or so. So he'll have nothing for 3 months and then 5 bies will come up within a couple of days.
He's not ill with it at all. But they do itch and sometimes you can see the patch around the mark is red and inflamed.
I've always been at a loss to explain them. I've checked his bed for mites, but there is no other evidence of them in or around his bed. I've aired his mattress outside as well as his duvet and pillows. I've changed all his bedclothes and pjs. In fact I did all of that just last week and yet last night the marks were there again.
Does anyone have any idea what they might be?
