In the last year my dd (2yo) has had reactions to raw tomatoes, cashews and peanuts. We are seeing the specialist next week for skin prick testing. This morning after breakfast I noticed my dd had a small red rash around her mouth. (Her dad gave her breakfast so I'm not exactly sure what may have caused it but she is unlikely to have had anything new.) It's now after lunch and the rash has spread a little and is more definted. It's still restricted to her mouth, chin and under her nose though.
Should I give her a dose of piriton or just wait for it to disappear? Skin prick testing is in a weeks time.
