Since you have not specified any specific areas of pain or whether in the muscles or joints, I would assume that you suffer from both types of pain and the pain is not restricted to a specific area of the body.
There is a possibility that you suffer from SLE or Systemic Lupus Erythematosus, which is the most common cause of joint and muscle pains. Most other infections and diseases that cause muscular or joint pains also display other symptoms. The pain is caused mainly by inflammation of the joints and muscles. The symptoms can at times resemble those of viral flu, like acute pain in the muscles and joints, making the person feel extremely sick. The symptoms could also bear resemblance to those of arthritis. In some cases there might not be very intense joint pains, but sever muscle inflammation could result in weakness. In very severe cases, the individual could experience pain even while resting. Patients have to be careful while engaging in any activity, that they avoid stress and pressure on affected joints and muscles.
Good self-care is important to managing lupus, and it's necessary to identify the warning symptoms of a flare, which could include increased fatigue, joint pains or fever. Stress can also be a trigger for lupus symptoms, and it's important to control your stress level, keeping it as low as possible.
