- redness, hives, swelling, itching
- 90% in USA population
- Taiwan study showed this to be less than 25% in their population. This is NOT a required sign.
- tongue/throat swelling
- larynx swelling
- difficulty talking or swallowing
- stridor, respiratory distress.
- cough, wheezing,
- SOB, WOB, respiratory distress.
- pallor, dizziness, hypotension, tachycardia
- loss of consciousness
- systolic BP below 90. (From a wilderness medicine standpoint this is easy to do as normo-thermic patients are recognized as having pedal pulses or warm feet if their systolic is 90 or greater.)

- nausea, vomiting, abdominal cramping,bowel incontinence
