Most of us suffer back pain at some point in our lives. In fact, it's one of the most common reasons people go to the doctor. Many of us also probably reach for medication. Now, new guidelines from the American College of Physicians say try exercise, yoga, or massage first.

That's a pretty big change for both doctors and patients, but a welcome one, some doctors say.

It's no surprise that most women with breast cancer consider hair loss one of the most traumatic aspects of chemotherapy. That has led to a big market for cooling caps, which are purported to limit hair loss.

But cooling caps haven't been extensively studied in the U.S., and womens' experiences with the caps have been hit or miss. And just one cooling cap, the DigniCap, is approved by the Food and Drug Administration.

It's tough to be a teenager. Hormones kick in, peer pressures escalate and academic expectations loom large. Kids become more aware of their environment in the teen years — down the block and online. The whole mix of changes can increase stress, anxiety and the risk of depression among all teens, research has long shown.

Most of us have reached for a painkiller, at one time or another, only to discover the date on the label shows it has expired. But what does an "expiration" date on medicine really mean? Is it dangerous if you take it anyway? Less effective?

So far, more than half of all U.S. states have legalized marijuana for medical use, and eight (plus the District of Columbia) have legalized the drug for recreational use. Varieties of cannabis available today are more potent than ever and come in many forms, including oils and leaves that can be vaped, and lots of edibles, from brownies and cookies to candies — even cannabis gummy bears.
