DD(7) has been getting hives daily for months now. Have seen GP and allergy clinic at hospital both just advised taking antihistamines. Today she was unwell and sent home from school with headache and a temp. Gave calpol and she improved, temp down. Hives developed with temp, has happened before. Gave antihistamines at 4pm. Hives are still red and itchy, have put calamine lotion on but can't give any more antihistamines. She can't sleep and is v uncomfortable. What do we do? is it worth taking her to A & E? Any advice appreciated.
