In brief: Swelling
Angioedema is a medical term for swelling of the deep layers of the skin.
Angioedema can be due to a number of different reasons and is not alway due to an allergy. In some cases, angioedema can be life threatening. An evaluation by an allergist can help determine the cause of angioedema.

In brief: Can be either
Allergic reactions can cause angioedema.
This is seen not infrequently in severe food allergies to peanut, tree nuts, and shellfish. The class of antihypertensives called ace inhibitors can also precipitate angioedema, but via a non-allergic mechanism. This would be classified as an adverse reaction.
