Muscle strains and sprains
Strains and sprains, whether acute or chronic, mostly have symptoms that are localized to the specific muscle groups or tendons. Pain in these conditions can involve a small area, or a larger area, such as a whole group of muscles. Interestingly, pain secondary to muscle strains and sprains is also accompanied by inflammation, muscle cramping, muscle spasm, and muscle weakness. This makes it easier to identify that the cause of your chronic pain lies in the muscles.
