Muscle pain causes are many and varied. The stiffness that many people describe as muscle pain can be pain coming from ligaments, tendons or nerves. There are two main causes for muscle pain and they have different medical names. Myalgia is a generic pain of a muscle. Myelitis is a pain in the muscles caused specifically by inflammation. Muscle pain can mean variety diseases and disorders, but luckily, it’s mostly benign pain after a workout.
Most of the muscle pain is caused by using the muscle improperly. We often give them a task they cannot perform. We push, pull or and lift things that are too heavy and thereby stretch and pull the muscle. When we exaggerate motions, the strands of fibrous tissue in our muscles stretch too much or even break. This happens to runners with the „groin pull“, or tennis players with the famous „tennis elbow“.
Don’t expect of your muscles to do too much too soon. Warm up well before any strenuous physical activity. Several diseases cause muscle pain too. Among most common are pneumonia, lupus, fibromyalgia, Lyme disease, malaria and few others.
