It happened today after he ate some smoked salmon so I, thinking he was having an allergic reaction- hot footed it to the GP's which thankfully only live a few minutes walk away. GP was very unhelpful and just said if it happens again give him some Piriton.
What happens if he has a severe reaction next time? Should I get him tested? The GP thinks it's pointless. Anyone else's DC have any experience of this? It's frightening!
