There are 2 Major Types of Angioedema:
 - Mast cell / histamine mediated – usually presents with angioedema AND allergic symptoms (urticaria, flushing, pruritis, bronchospasm, throat tightness, hypotension)
 - Bradykinin mediated – presents WITHOUT allergic symptoms, usually history of recurrent swelling; think ACEi
