Scorpion Stings
Introduction
The stings of North American scorpions are rarely serious and usually result in pain, minimal swelling, tenderness, and warmth at the sting site. However, the bark scorpion (Centruroides exilicaudaorC. sculpturatus), which is present in Arizona and New Mexico and on the California side of the Colorado River, has a much more toxic sting. The sting is painful, sometimes causing numbness or tingling in the area around the sting. Serious symptoms are more common in children and include Abnormal head, eye, and neck movements Increased saliva production Sweating Restlessness Some people develop severe involuntary twitching and jerking of muscles and very high blood pressure. Breathing may become difficult. (See also Introduction to Bites and Stings .)
