Unsweetened cocoa powder has variable amounts of health-promoting flavanols, depending on how it is processed. Fruits and vegetables are better sources of these compounds, which may improve blood pressure and blood sugar.

People with knee osteoarthritis often gain temporary pain relief from joint injections. However, there is uncertainty about long-term risks of steroid injections. A 2022 study suggests that the risk may be minimal if these injections are done infrequently.

Ticklishness falls into two categories: gargalesis (which produces laughter and squirming) and knismesis (the sensation of a feather brushing over the skin, also known as light-touch tickling). It is not clear why some people are ticklish, but it may be a bonding or protective reaction.

A troubling aspect of COVID infection is long COVID, also known as post-acute sequelae of SARS-CoV-2 infection, or PASC. PASC is marked by persistent symptoms 30 days or more after a person tests positive for COVID. Also, symptoms suggestive of PASC may emerge many weeks after recovery from the initial infection. Scientists are still learning about PASC, but they have discovered much so far, such as who may be at higher risk, what symptoms are common, how long it may last, and what people can do to protect themselves.

While not as routine as cataract surgery, corneal transplants are becoming more common. A number of things can go wrong with the cornea, especially as people get older, and a partial-thickness or full-thickness transplant can restore vision.

Women are more likely to get acne after age 20 than men. Unfortunately, treatment options that worked in the teenage years may not work as well in adult females. The emotional toll of acne may include a higher risk of developing depression, and having severe acne can negatively affect quality of life.

Migraines can last hours or days and span several distinct phases. A post-headache phase leaves as many as four out of five migraine sufferers feeling like they have a hangover. Experts recommend different approaches to help ward off lingering symptoms depending on their intensity.

Among people with chronic heartburn, sleeping on the left side appears to help backed-up stomach acid leave the esophagus faster than sleeping on the right side or back, according to a study in the February 2022 issue of The American Journal of Gastroenterology.

When doctors say that it's okay to take proton-pump inhibitors (PPIs) "on demand" for chronic heartburn, the advice doesn't apply to everyone. PPIs inhibit the production of stomach acid, which can back up into the esophagus and can cause pain (heartburn) and damage the lining of the esophagus. People with damage to the esophagus often stay on PPIs long-term to prevent further problems. People without damage to the esophagus can take a short course of PPIs as needed.

Nighttime skin itching can stem from dry skin, hormone changes, certain medications and skin care products, and rarely, a more serious illness. It can help to change bedding or pajamas, take short baths or showers, apply moisturizer liberally, and use a humidifier.
