Hi, my husband had a really bad reaction to something last night. His face, neck, chest and parts of his arms and back turned a bright red, almost purple. He had shortness of breath, coughing, rapid heart beat and vomitting. It lasted about an hour. This isnt the first time its happened. He also had about 6 - 7 beers as well. He wont go see a doctor. What could this be? As far as he knows he's not allergic to anything....
