This is an allergic skin disease caused by eating shrimp or crab, administration of drugs or parasite in the body. Symptoms include the sudden appearance of skin lesions all over the body, and even over the mucosa. The lesions may disappear without a trace left on the skin after a few hours. Later, the skin lesions may reappear again, group by group. In chronic patients the skin lesions may relapse in several weeks, months, or even over several years. The skin lesions are slightly bulged papules warying in size from the sesames to beans, or even as large as walnutts, and they may increase in size after scratching. Besides the local burning sensation and severe itching, patients may also suffer from nausea, vomiting, abdominal pain, diarrhea and other digestive tract symptoms if the lesions appear on the mucosa of the stomach and intestines, and severe cases may develop edema of the throat with dyspnea and syncope.
