DS has hayfever, asthma and allergies. Tonight he's been itching his eyes every so often but not loads and it doesn't seem to have been bothering him much. However in the last twenty minutes or so his eye has become really swollen. I put it down to his hayfever and didn't think much of it. But I've just checked on him and he now has three big lumps on the top of his eyelid. Could this be hives from rubbing his eyes a bit earlier or should I be worried he's been bitten or having a reaction to something else?
