Most scorpion stings in the United States cause only minor signs and symptoms, such as pain and warmth at the sting site. The venom of the bark scorpion, native to Arizona, New Mexico and the California side of the Colorado River, is more toxic and can be life-threatening, particularly in children.
Mild signs and symptoms might include:
- Pain, which can be intense
- Numbness and tingling in the area around the sting
- Slight swelling in the area around the sting
More-severe signs and symptoms might include:
- Muscle twitching or thrashing
- Unusual head, neck and eye movements
- High blood pressure (hypertension) or low blood pressure (hypotension)
- Accelerated heart rate (tachycardia) or irregular heart beat (arrhythmia)
- Restlessness or excitability or inconsolable crying (in children)
