Muscle pain (myalgia) are pulling, gut-wrenching and spasmodic pain in the muscles: the term myalgia is composed of the Greek words myos for muscle and algos for pain. Muscle pain can spread (diffuse) or (local) occur in a certain place of the body.
Myalgia translates to muscle pain. It is fair to say that most people experience one or two cases of the condition, at least, in a lifetime. Most often the pain is caused by straining or overuse of a muscle. It can occur in any muscle group, at any time of life. Myalgia that is not caused by muscle strain can be present in a large number of infectious diseases, anything from the common influenza to illnesses like Lyme disease.
