Healthy feet are the foundation of an active lifestyle, but many people don't give their feet proper attention. Regular foot maintenance can help prevent pain and injuries and protect against infections. Helpful steps include maintaining basic foot hygiene, performing regular foot exercises, and wearing properly fitting shoes.

Strength training triggers many body reactions that protect people against chronic disease. For example, strengthening muscles helps reduce blood sugar, lower blood pressure, burn calories, and discourage chronic inflammation. Evidence suggests that getting 30 to 60 minutes of weekly strength training leads to the highest amount of health benefits. That's in line with the recommendation from the 2018 Physical Activity Guidelines for Americans. But doctors say any amount of strength training can help health.

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.

Knuckle cracking doesn't "crack" a joint. The sound comes from gas bubbles bursting in the fluid inside the joint. While knuckle cracking is mostly harmless, other types of noises or the presence of pain can indicate a more serious joint problem.

Osteoarthritis in the hand is a painful condition that is more common in women than in men. While this condition can be debilitating, a number of strategies can be used to manage it, including using various topical, oral, and injected pain medications; splinting the joint; making lifestyle changes; and working with a hand therapist. Surgery may be an option when other measures have failed to control symptoms.

Experts suggest people replace their walking shoes every 300 to 500 miles. For the best selection and advice, people should consider shopping at a specialty running store that also sells walking shoes. Other tips for choosing comfortable, supportive shoes include looking for low-heeled shoes that bend easily at the ball of the foot and have wiggle room at the toes.

Toenail fungus is difficult to cure without resorting to oral treatments that can affect liver function. Topical treatment can improve nails' appearance.

Many conditions affect the feet and can cause pain. Five common problems are bunions, fallen arches, hammertoes, ingrown toenails, and plantar fasciitis. Fortunately, there's a wide range of treatments for relief. New approaches include stretching the calf muscles to improve the way feet fit into orthotic insoles; shock-wave treatment for plantar fasciitis; and minimally invasive surgeries for bunions and hammertoes that involve small instruments and incisions. Tried-and-true therapies include soaking feet when an ingrown toenail causes pain, or wearing a splint at night for plantar fascitis.

Common causes of cold feet include clogged arteries in the legs (peripheral artery disease), low body fat, Raynaud's syndrome, and nerve damage.

The first-ever guidelines to diagnose chest pain document the range of possible heart attack symptoms. They include a sense of pressure, tightness, squeezing, or heaviness in the chest but also in the shoulders, arms, neck, back, upper abdomen, or jaw. The report also provides a road map to help doctors assess chest pain with selective use of the latest available tests. Chest discomfort can also result from other conditions that affect the heart (such as pericarditis) and nearby organs. These include acid reflux, muscle or joint issues, and lung problems.
