Pain relief refers to the methods and treatments used to reduce or eliminate discomfort caused by various conditions, injuries, or illnesses. It can involve medications, physical therapies, or alternative approaches like acupuncture. Common pain relief medications include nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids, which target pain signals in the body. In addition to medications, non-drug therapies such as physical therapy and massage can help alleviate pain by improving mobility and reducing muscle tension. Lifestyle changes, including regular exercise and stress management techniques, also play a crucial role in managing pain effectively.
