Angioedema: Angioedema is a severe swelling beneath the skin, especially of the face and the limbs. Sometimes, rashes also appear along with the swelling. Other symptoms are swelling of the eyes or eyelids and lips, stomach cramps, and difficulty breathing.
Emotions, like fear and love, are carried out by the limbic system, which is located in the temporal lobe. While the limbic system is made up of multiple parts of the brain, the center of emotional processing is the amygdala, which receives input from other brain functions, like memory and attention.
Thus, physical evidence has revealed that the right hemisphere, while indeed the brain's more emotional side, is not solely responsible for processing the expression of emotions. However, the left brain stays active to categorize or label the emotion -- as befits its dominance in language processing.
