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.

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.

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.

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.

Platelet-rich plasma injections are used to reduce pain and speed healing for a number of common problems that affect the tendons, muscles, and joints, ranging from arthritis to shoulder pain. But a growing body of research shows that they may not be effective for some conditions, including knee osteoarthritis, ankle osteoarthritis, and Achilles tendinitis.
