There are a number of different approaches to treating a condition called adhesive capsulitis, better known as frozen shoulder. This common condition causes significant shoulder pain and reduced mobility. While it generally goes away on its own over time, it can take up to a year or longer to heal. But there hasn't been consensus on whether any particular therapy leads to more rapid pain relief and full range of motion.

A study published online Dec. 16, 2020, by JAMA Network Open looked at various treatment options for frozen shoulder to determine which was the most effective. Researchers analyzed 65 different studies with more than 4,000 total participants and found that the first line of therapy should be to inject a steroid directly into the joint to reduce inflammation. This treatment helped to reduce pain and led to the fastest recovery. The study authors said the steroid injection should be accompanied by a home exercise program that includes stretches and exercises to improve range of movement in the shoulder.

The foods you eat (and don't) can determine how well your body fights painful inflammation.

It's been said that you are what you eat, and that's definitely true when it comes to chronic pain.

"A lot of chronic pain is the result of chronic inflammation, and the evidence is quite strong that your diet can contribute to increased systemic inflammation," says Dr. Fred Tabung, a visiting researcher with the Department of Nutrition at Harvard's T.H. Chan School of Public Health. "But your diet is also one of the best ways to reduce it."

Pillows can help or hurt, depending on their firmness and your sleep position.

You probably know someone who won't leave home without a special pillow, claiming that a particular bag of fluff or feathers is the key to a good night's sleep. And that person may be on to something. "Anything that will make you more comfortable will improve the likelihood of getting a good night's sleep," says Dr. Lawrence Epstein, a sleep expert at Harvard-affiliated Brigham and Women's Hospital.

But the benefits of pillows don't go much further than comfort and positioning. Sometimes pillows even hurt your health.

Back pain is one of the top reasons that people begin to lose mobility in middle age. Pain can keep people from engaging in physical activity, making it more difficult for them to maintain a healthy weight and keep up their strength, stamina, and balance as they age. So treating and managing back pain that results from injuries or health problems is crucial for staying on the path of a healthy and active life.

Considering that most people spend roughly a third of their lives lying in bed, choosing the right mattress is essential for managing low back pain. It can make the difference in whether you can sleep at night and function the next day.

Q. My friend was recently diagnosed with fibromyalgia, but it seems like she might be imagining her symptoms. Is fibromyalgia a real condition?

A. The short answer to your question is yes. Fibromyalgia is a real condition that affects some four million Americans. It's a chronic pain syndrome that experts believe may be caused by a malfunctioning nervous system. Researchers using magnetic resonance imaging to examine the brains of people with fibromyalgia have found abnormalities in the part of the brain that processes pain signals from the body. It appears that this part of the brain is essentially boosting the intensity of normal pain signals, potentially causing the body to feel pain without a physical cause.

An ailing knee or a hip can make life miserable. Even if your doctor recommends it be replaced, you need to carefully weigh the risks and benefits before agreeing to this major surgery and understand that it will require significant rehabilitation to get back on your feet.

The most important factor in choosing to have a knee or hip replaced is how much it hurts and how much it is affecting your life. Here are six signals that it's time to have a knee or hip replaced:

The first line of treatment for many knee and hip problems includes taking over-the-counter pain medications. Acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen are the most common pain medication options. However, these pain medications have a variety of side effects, so it's important to discuss your personal health risks with your doctor when considering long-term use for chronic conditions such as osteoarthritis.

Acetaminophen (Tylenol and other brands) is usually effective for mild pain and is easy on the stomach. However, it is toxic to the liver at high doses. The recommended maximum per day is generally set at 4 grams (4,000 milligrams), which is the equivalent of eight extra-strength Tylenol tablets. But that dosage can still cause liver problems for some people. To be safe, aim for 3,000 milligrams or less, and be cautious of mixing multiple products containing acetaminophen, such as a pain reliever and a cold medication or a prescribed narcotic.

You've run out of options for hip pain and you're facing a possible hip replacement (see "Anatomy of a hip replacement"). Once your doctor has determined that you're a good candidate for surgery — based on your medical history, images of your hip, steps you've taken to reduce pain (such as weight loss and low-impact exercise programs), and how pain has affected your daily function — you'll need to ask lots of questions.

"This is not a time to be shy. Be aggressive and get answers. The doctor expects that," says Dr. Scott Martin, an associate professor of orthopedic surgery at Harvard Medical School and medical editor of the Harvard Medical School Guide Total Hip Replacement.

Strengthening your core using plank exercises can help ease back pain. The plank position is essentially the high part of a push-up. People who can't hold this position can try a modified version by bending their knees and resting them on the ground. Build strength by practicing holding a plank for as long as you can, and then progressively working to hold it for longer each time.

Here's what to expect once you're home from the hospital.

Every day, thousands of people in the United States undergo open-heart surgery. This major operation leaves them with a long chest incision — and a lengthy recovery. The time it takes to fully heal will depend on the person's age and overall health and the complexity of the operation.

The most common is coronary artery bypass grafting, which uses a blood vessel taken from another part of the body to bypass a blocked heart artery. Open-heart surgery is also done to repair or replace a faulty heart valve or to repair damaged or abnormal areas of the heart.
