Symptoms can include hives, sneezing, coughing, itching, runny nose, "pins and needles" sensation of the skin, dizziness, nausea, vomiting, diarrhoea, abdominal pain, loss of consciousness, flushing, facial oedema, swelling of mouth and throat, urticaria, anxiety, respiratory difficulties and hypotension, which may progress to shock and collapse. Cardiovascular collapse can occur without respiratory symptoms. Early recognition and treatment of anaphylaxis is vital. If hives and facial redness are the only symptoms, and attacks are rare, the disease can be cured with hormone injections.
