Introduction • There are several ways to define pain. • Pain depends on many factors such as culture, environmental, and emotional; Pain is how you respond to an unpleasant sensation. This explains why some people handle pain better than others. • Chronic pain- Long-term pain such as arthritis • Acute Pain- A temporary pain like such as stubbing your toe. • Pain is a survival mechanism. Warns something is wrong.
Statistics • In America, 50 million residents live with chronic pain. • Pain forces around 36 million of these residents to miss work every year. • Pain results in approximately 70 million doctor visits per year.
Shutting Off Pain • New lab experiments have shown it is possible to turn off pain sensitive neurons using an agent that acts as a photosensitive switch. • The chemical QAQ (ammonium-azobenzene-quaternary-ammonium) forms this switch to turn off pain. • Half of QAQ resembles one of the active parts of lidocaine which is a local anesthetic commonly used at the dentist.
Light • They activate and inactivate the pain by certain rays of light. • The light silences the neurons in our body that sense pain.
