Analgesia is the loss of pain without the loss of consciousness.

Techniques for controlling and relieving pain include acupuncture, anesthesia, hypnosis, biofeedback, and the use of analgesic drugs. Acupuncture is the ancient Chinese practice of inserting fine needles along certain pathways of the body and is used to relieve pain, especially in surgery, and to cure disease. In Western medicine the discovery of ether was a landmark in the development of anesthesia. Other techniques for pain control include electrical stimulation of the skin, massage, and stress-management therapy.

Analgesia is of primary importance for the treatment of injury or illness. The main agents for accomplishing analgesia in medical practice are analgesic drugs. These fall into two main categories: addictive and nonaddictive. Nonaddictive analgesics are generally used for treating moderate to severe pain and can be purchased without a prescription as over-the-counter drugs. More powerful analgesics have the potential for addiction and other undesirable side effects. They are usually used in hospitals or prescribed for relief from severe pain.

Presently, efforts are underway to develop powerful nonaddictive pain-relieving drugs. In order to improve the effectiveness and minimize the harm of analgesic drugs, pharmacological research has focused on the mechanism of how analgesics accomplish the task of pain relief. Mechanism in this context means the way the drug works in the body to accomplish its results.
