People diagnosed with<unk>  have recurrent swelling in the extremities, genitals, face, lips, larynx or GI tract. Some patients describe a sensation of fullness but not pain or itching in the affected area except for those with abdominal swellings who often experience acute abdominal pain. Others experience an intense amount of pain, described as radiating from the bone outward along with intense itching just beneath the skin and intense heat, regardless of the area targeted. Swelling involving the respiratory and gastrointestinal systems can cause significant risk and distress. Involvement of respiratory structures, such as the throat or larynx, can cause difficulties in breathing and life-threatening airway obstruction. Episodes that attack the gastrointestinal tract can cause a number of complications including vomiting, crampy abdominal pain, diarrhea, and dehydration. Some sufferers of<unk>  experience 'wandering' attacks. These attacks will center around an extremity. For example: Should the sufferer's hand swell up, it will go through the normal swelling cycle before 'transferring' to either the connection limb (In this case wrist to forearm) or move to the opposite hand. Sufferers with this symptom may find their episodes last longer and may find their triggers more difficult to track.
