Muscle pain is most frequently related to tension, overuse, or muscle injury from exercise or physically-demanding work. In these situations, the pain tends to involve specific muscles and starts during or just after the activity. It is usually obvious which activity is causing the pain.
Muscle pain also can be a sign of conditions affecting your whole body, like some infections (including the flu) and disorders that affect connective tissues throughout the body (such as lupus).
One common cause of muscle aches and pain is fibromyalgia, a condition that includes tenderness in your muscles and surrounding soft tissue, sleep difficulties, fatigue, and headaches.
Regular exercise can help restore proper muscle tone. Walking, cycling, and swimming are good aerobic activities to try. A physical therapist can teach you stretching, toning, and aerobic exercises to feel better and stay pain-free. Begin slowly and increase workouts gradually. Avoid high-impact aerobic activities and weight lifting when injured or while in pain.
Be sure to get plenty of sleep and try to reduce stress. Yoga and meditation are excellent ways to help you sleep and relax.
If home measures aren't working, call your doctor, who will consider prescription medication, physical therapy referral, or referral to a specialized pain clinic
