Most species of scorpions are not dangerous, but some in South America, India, the Caribbean, the Southern US and North Africa are extremely venomous. Certain stings can cause only mild pain and tingling; but in more venomous species severe pain, sweating, diarrhoea, vomiting and restlessness can occur. They are hardly ever fatal in adults, but pose a bigger risk to children and the elderly.
Scorpion stings need prompt attention. If pain is the only symptom, a cold compress and analgesics can be all that is needed. In extreme cases, treatment with antivenom can be required.
