In brief: Mild to severe

Because allergy injections expose patients to proteins known to cause symptoms, there is always a reaction risk.
Most reactions are local & involve redness, swelling, tenderness, & itching. Occasionally the reaction becomes body-wide and shows up as hives, wheezing, chest pain, or dizziness. In rare instances, the reaction may become life-threatening. This is why there is a wait time after shots.

In brief: Allergy Shots

Allergy symptoms might get worse during the building phase, local redness, swelling and itching at injection site, asthma symptoms.
...And the most severe is anaphylaxis...Rare but that is why you need to have an epi-pen.
