A Sting

 What it is: Usually an irritation, not an emergency―unless you're allergic. But even in someone who's not allergic, a sting in the wrong place can cause problems.
 
 What to do at home:
 

• If you're stung on your hand, immediately remove any rings so they don't impede blood flow caused by swelling (and so you don't risk having your wedding band snipped off).
• Remove the stinger by scraping the skin (try a credit card held perpendicular to the skin). Don't grasp the stinger; this can force out more venom.
• Elevate the area of the sting and apply ice.
• You can take ibuprofen (such as Advil) or acetaminophen (Tylenol) for pain, and an over-the-counter antihistamine containing diphenhydramine (Benadryl) if the itching is bothersome. Hydrocortisone cream can also help.

 Seek immediate help:

• If you experience throat swelling or tightening, generalized hives or itching (not just at the sting), wheezing, or light-headedness. These are signs of an allergic reaction, a true emergency. Call 911.
• Stung on the face or neck? Go to the ER if you are wheezing or feel as if your throat is closing; swelling may block your airway.
