Lower back muscle tightness is the cause of a muscle spasm. This can be brought on by a strain, overuse or muscle weakness, according to BetterMedicine.com. If your lower back muscles lack strength, and a stronger back muscle pulls on this weak muscle, it can create tightness or pain. While lower back tightness can be managed at home, occasionally medical intervention is needed to treat this common condition.
Rest your lower back muscles. Lie in a comfortable position that reduces tension in your lower back and does not twist or bend your spine. Avoid strenuous or physical activities until the tightness is gone.
Use cold and hot therapy on your lower back. Apply an ice pack to your muscles for the first two days for 15 minutes, three times a day. Use a hot compress on the third day.
Quit smoking. Smokers have lower oxygen levels in their spinal tissues. This lack of oxygen can delay the healing process.
Massage your lower back muscles. Massage helps to relax your lower back and loosen up knots in your muscles. Use your fingers to massage the tight spots in your lower back with gentle pressure.
Make an appointment with your doctor. Your doctor can diagnosis your lower back tightness, provide physical therapy stretches and prescribe medications. In some cases, injections and surgery are used to help improve muscle function and reduce tightness and pain.
