He is staying at Grandad's and phoned yesterday to say that his lips had swollen (Dad was eating cashews) so it must have just been a fleck that somehow got on his lips or in his mouth. I told him to take an antihistamine which was reducing the swelling when we last spoke. I told my Dad to keep an eye on him.
Is there anything else I need to know here? What could have happened? Should we have monitored him more closely? I guess we don't need to tell the doctor?
It's only the second time it's happened. We established that he had a nut allergy after the first time so he's never needed an epi-pen. I guess we can add cashews (which he wasn't tested for) to brazils and walnuts as the problem but the doc said no nuts anyway.
