Sales of cannabidiol-infused products are expected to top $2 billion by 2021. But is CBD right for you?

Cannabidiol (CBD) is touted as a natural wonder that can help treat symptoms of everything from anxiety to arthritis pain. The plant extract comes from two varieties of cannabis — hemp and marijuana — and is available in creams, tinctures, oils, patches, gummy bears, capsules, and more. You can even add CBD to a latte if you walk into a coffee shop in some cities.

But is CBD safe for older adults? There haven't been a lot of large studies of CBD's safety, but more traditional medicines for pain and anxiety are not free of adverse effects, either. "I think CBD is likely safer than many other treatments people use for pain, insomnia, or anxiety," says Dr. Peter Grinspoon, a primary care physician with Harvard-affiliated Massachusetts General Hospital. Other physicians don't think we know enough about the safety profile of CBD to be sure.

Here's what you can do about the three most common foot issues related to aging.

When our feet hurt, we hurt all over. That saying is often attributed to the Greek philosopher Socrates, and it's as relevant today as it was more than 2,500 years ago.

"Our feet are our vehicle to an active lifestyle," says Dr. Christopher DiGiovanni, chief of the Foot and Ankle Service at Harvard-affiliated Massachusetts General Hospital and Newton Wellesley Hospital. "If your feet are not sound and healthy, it's tough to keep the rest of you healthy, too."

Ask the doctors

Q. My friend insists that her arthritis pain gets worse just before it rains. Is it true that joint pain can intensify based on the weather?

A. Despite what your friend, your grandmother, and generations of people have sworn is the case, experts haven't found consistent evidence that arthritis pain gets worse on rainy days. At best, study results over the years have been mixed, and one large, recent study seems to cast doubt on the theory.

Research we're watching

If you have an arthritis-related condition called Heberden's nodes, you may be at higher risk for arthritis-related knee problems, according to a study published online January 9 by Arthritis & Rheumatology.

Heberden's nodes develop when cartilage in the fingers wears away, causing the bones to rub against one another. This prompts new bone to form, creating bony nodules in the knuckles closest to the fingertips.

Hip and knee pain can keep you from the activities you love, as well as make routine tasks difficult. But there are many ways to get you moving again pain-free, without surgery. Here are some of the treatments that can help relieve hip and knee pain.

Ultrasound, phonophoresis, and iontophoresis

Therapeutic ultrasound is a simple procedure that uses sound waves to increase blood flow, relax muscle spasms, and aid healing that leads to faster hip pain relief and knee pain relief. The therapist applies gel to your skin and moves an ultrasound wand over your skin around the painful area. In a special ultrasound technique called phonophoresis, medication (often hydrocortisone) is added to the gel. In a survey of orthopedic physical therapists, more than half said they would use ultrasound and phonophoresis to reduce soft-tissue inflammation (in tendinitis or bursitis, for example). These techniques are also used to manage pain, heal tissue, and help muscles stretch.

Osteoarthritis, the most common form of arthritis, occurs when protective cartilage inside a joint wears down. This type of arthritis is unheard of in children and is rare in young adults, but often occurs in older people and people who are overweight. Because of this, osteoarthritis was long considered a natural product of aging and everyday wear and tear on joint cartilage.

However, many experts now believe the cause is much more complex. External factors, such as injuries, can set the stage for osteoarthritis, but how fast it progresses and how severe it becomes depends on a number of factors. Here are just a few factors that can increase your osteoarthritis risk.

Many people with rheumatoid arthritis (RA) also deal with ongoing depression and anxiety related to their pain and disability. While drugs used to treat the disease help alleviate the joint pain and stiffness, a recent study suggests they may not extend to improving patients' mental health.

The findings, published online June 6, 2018, by Arthritis & Rheumatology, reviewed more than 70 clinical trials and found only a small association between various drugs used for RA, such as adalimumab (Humira), rituximab (Rituxan), abatacept (Orencia), and tocilizumab (Actemra), and mental health outcomes in patients.
