Hi, I am 51 and in the last 3 months have developed a reaction to certain foods - pale patches under the eyes with excema and sometimes urticaria . The foods in question seem to be fish, dairy and beans. Blood tests came up negative for allergies to these or any other foods, but the symptoms persist. What could be the reason and what can I do about it? I have been to my GP, a dietician and a homeopath and nobody seems to have an answer. Can you help?
