Galveston County Daily News (Internet / Print) 05/04/06 Weekly Column by Dr. Sally Robinson and Dr. Keith Bly: Spring is here, and with it comes warm weather, more daylight — and bugs. Many insects have bites or stings that can cause problems, but the key to treating the problems is in understanding the difference between a bite and a sting. If your child experiences a large area of swelling, abnormal breathing, tightness in the throat or chest, dizziness, hives or rash, fainting, nausea or vomiting or pain and swelling that lasts longer than 72 hours, he or she may be having an allergic reaction to the sting or bite and you should seek immediate medial attention.
