I myself recently found out that i am allergic to hamburger i'm supposing its beef in general as i only eat my burgers well done. however its only the beef that is store purchased and is ground. i can go to McDonald or any fast food restaurant and order a burger and be fine. if i eat home made patties i break out in bumps, itch horrible, and even swell in my hands and face. last week i ate burgers and i done all of the above and even vomited so im still trying to figure out what i can do to eat burgers again as they are my favorite. any one out here have a solution to this problem?
