Raynaud's phenomenon—an extreme reaction to cold—can be annoying, or it may signal a serious chronic condition.

If you live in the northern latitudes, you may have already had an episode in which your fingers froze or your nose, toes, or earlobes grew cold, pale, and numb. And if you're a southerner, you might have neighbors who migrated to avoid such episodes. While some people with chilly fingers just have cold sensitivity, others—especially women—may have Raynaud's phenomenon.

What is Raynaud's?

Living with Raynaud's

Your ability to grab, hold, twist , and squeeze is essential for many everyday functions.

Think how much you rely on a strong grip every day. It helps you open cans, grip a golf club, hold a steering wheel, brush your teeth, and pick up a grandchild. "The ability to stay active and independent often begins with our hands," says Maria Cole, a physical therapist with Harvard-affiliated Spaulding Outpatient Center. "Weak grip strength can limit your enjoyment of many life pleasures, so you need to ensure your hand and grip strength always are up to the task."

A measure of health

Exercise your hands

It appears that “unloading” shoes are no better at reducing pain or improving function than a good pair of walking shoes, according to a study published online July 12, 2016, by Annals of Internal Medicine. 

Forgoing drugs that slow bone loss to avoid rare side effects can be the wrong decision for your hips and spine.

A front-page article in the June 1, 2016, edition of The New York Times carried this headline: "Fearing drugs' rare side effects, millions take their chances with osteoporosis." The article described a situation all too familiar to doctors. Women are declining prescriptions of bisphosphonates—drugs that slow the rate at which the body breaks down bone—or discontinuing the medications far earlier than recommended. In fact, according to a 2015 report in the Journal of Bone and Mineral Research, the rate of bisphosphonate use fell by half between 2008 and 2012. That article documented a wave of media coverage of scientific studies that reported two rare side effects—osteonecrosis (bone death) of the jaw and atypical fractures near the top of the femur (thigh-bone)—and suggested that the reports had kindled fears that had led women to abandon bisphosphonates.

"The perception of risk is so much greater than the actual risk," says Dr. Meryl LeBoff, director of the skeletal health and osteoporosis center at Harvard-affiliated Brigham and Women's Hospital. Compared with many other common diseases, we are fortunate that we have good therapies to reduce the risk of osteoporotic fractures by 70% at the spine and 40 to 50% at the hip. She points to statistics referenced in the New York Times article: for every 100,000 women taking a bisphosphonate, fewer than three will have osteonecrosis of the jaw and one will have an atypical femur fracture, but 2,000 will have avoided an osteoporotic fracture.

These options may help you find relief from constant discomfort.

Knee pain is one of the top reasons men visit their doctor. While the pain and soreness often can go away with rest, ice, and over-the-counter pain medications, if it becomes too severe or fails to abate in a timely manner, you may need to take further action.

"If your knee pain is not a result of some kind of structural or mechanical issue that requires surgery, or due to osteoarthritis, there are other options that may help eliminate or better control the pain," says Dr. Lars Richardson, a sports medicine orthopedic surgeon with Harvard-affiliated Massachusetts General Hospital.

A few simple exercises can preserve the strength and flexibility of your hands and wrists.

There's a reason that "having a good grip on the situation" is used as a metaphor for mastery. In physiological testing, grip strength is one of the indicators of health and vitality. Yet, although we may exercise to strengthen our cores and limbs, most of us don't make an effort to strengthen our forearms and our hands. "We use our hands continually, but we don't take the time to deliberately exercise them," says Joanne P. Bosch, a physical therapist and certified hand therapist at Harvard-affiliated Brigham and Women's Hospital.

That said, it's not a good idea to rush out and buy a device promoted for building a "crushing hand grip" or to start squeezing a tennis ball. "Doing the wrong exercise can actually exacerbate some problems, particularly carpal tunnel syndrome," Bosch says.

A recent journal article describes Michelangelo’s hands as depicted in an attempt to figure out potential joint diseases he may have had. Theories suggest some myths and misconceptions about the causes and symptoms of osteoarthritis and gout. This report has implications for today’s medical care. While a picture may tell a story, there is nothing like a thorough, in person exam to know accurately make sense of signs and symptoms.
