Pain relief is a term used to describe the relief of physical pain. ASPIRIN (7 letters) and Analgesia (9 letters) are two common methods of pain relief. ASPIRIN is an over-the-counter medication that works by reducing hormones that cause pain and inflammation in the body. Analgesia is a medical term for the relief of pain without the loss of consciousness. It can be achieved through the use of medications, such as opioids, or through the use of non-pharmacological methods, such as acupuncture.
