Another important reminder that just because a medication is sold "over the counter" doesn't mean it comes without any potential risks: new data coming out of Brigham and Women's Hospital and Harvard Medical School suggests that most commonly used painkillers can increase your risk of high blood pressure.

The painkillers tested included pretty much all of them, including those sold under the names Aleve, Naproxen, Ibuprofen, Motrin, aspirin, and even Tylenol.

Of course this doesn't mean you should suffer by passing on the pain meds altogether, but it does warrant regular conversations with your doctor if you need painkillers frequently -- maybe there are other ways to treat your symptoms.
