Arthritis

This is a classic example of being caught between a rock and a hard place. You're getting older, your joints are creaky and you're in some pain. So, like many of us, you take non-steroidal anti-inflammatory drugs (commonly called NSAIDs). But then you develop another problem: erectile dysfunction.

Do your joints feel stiff and achy when you wake up in the morning? If the answer is yes and you're over 45, you could be suffering from osteoarthritis, a disease in which the cartilage between bones breaks down, causing joint pain.

According to a recent report by the Centers for Disease Control (CDC), about 22 percent of American adults have been told by a doctor that they have arthritis – which means that nearly 50 million people have been diagnosed with the disease.
