Pain Killers are a staple in almost every person's medicine cabinet. Aches or pains? We pop a pill with nary a thought towards what we're putting into our body. But it's important to know what you're putting into your body. Here's a quick run-down of the popular pain killers on the market:

• Aspirin can reduce fever, pain and swelling, and it's also been proven to help prevent blood clots, strokes and heart attacks. However, it's not right for everyone--it can cause Reyes syndrome in teenagers--so talk to your doctor first.
  
• Ibuprofen can reduce fever and mild pains, but in some cases, it has been shown to cause stroke and heart trouble. It's also hard on the stomach.
  
• Acetaminophen, the active ingredient in Tylenol, is good for relieving mild fever and pain, but be sure to adhere to the dosage guidelines, especially when giving it to children.
