Answer:
Anaphylaxis causes your immune system to release a flood of chemicals that can cause you to go into shock — your blood pressure drops suddenly and your airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting.
Step-by-step explanation:
Signs and symptoms of anaphylactic reactions include: moderate to severe dyspnea, tightness in chest, wheezing, muffled voice, stridor, generalized hives, generalized pallor or flushed skin, swelling of face, lips, eyes, tongue, mouth, injection site, tachycardia, hypotension, tachypnea, and decreased oxygen saturation.
