Which therapy is used to alleviate pain by applying cold to the affected area?

Cryotherapy is a therapeutic technique that involves the application of cold to the body, typically to reduce inflammation and alleviate pain. This method works by causing vasoconstriction, which reduces blood flow to the area, thereby decreasing swelling and numbing the nerve endings to provide pain relief. It is commonly utilized in sports medicine for acute injuries such as sprains or strains, where swelling and pain are often immediate responses.

This approach differs from heat therapy, which uses warmth to relieve pain typically associated with chronic conditions or muscle stiffness. Massage therapy focuses on manipulating the muscles and soft tissues to alleviate tension and promote relaxation, while rehabilitation therapy aims at restoring function and is more structured around exercises and physical training. Each of these other options serves different purposes and has distinct applications in the realm of pain management and recovery.
