When symptoms of back fever occur, you can first consider the presence of infection and inflammation in the soft tissues of the back. Infection refers to the infection of the soft tissues of the back, including the skin and subcutaneous tissues, and back fever is accompanied by symptoms of redness and pain in the back. Back fever is usually caused by an infection, which can be caused by trauma, skin breakdown, or other routes of infection such as the flu. If the soft tissues of the back, such as the myofascia, are irritated by cold or moisture, this can lead to non-infectious inflammation of the soft tissues and localized chronic exudation, which can also lead to fever in the back. This may be accompanied by localized pain, or simply muscle tension in the back, as well as a fever in the back. Therefore, once the symptoms of back fever appear, you should go to a regular hospital in a timely manner and get treatment after diagnosis.
