👉 Rachianalgesia is a condition that refers to pain or discomfort from the use of certain materials, such as metal, rubber, or plastic. It can also refer to the sensation of a small amount of heat or cold when using these materials. Rachialgesia occurs due to irritation or damage to the skin caused by the material being used. This condition is often associated with prolonged exposure to certain types of metals, particularly those found in industrial applications such as metalworking and construction.
