Severe lower back spasms are often caused by strained muscles, according to Spine-health.com. These muscle spasms can be a short-term problem or more chronic. Treatments typically include rest, immobilisation, medication, heat and exercise.
Individuals that have severe muscle spasms in their lower back try resting for a few days. The best way to rest is on the back with a pillow under the knees.
Heating pads can provide temporary relief for back spasms as they relax the muscles and nerves, according to Familydoctor.org. One should use a heating pad or lie in a hot tub of water for 20 or 30 minutes several times per day.
Anti-inflammatory medications such as naproxen, ibuprofen and aspirin can help relieve severe muscle spasms and pain. These medications can usually be taken every four to six hours as needed.
Simple stretching exercises like lying on a hard floor and pulling one or both knees to the chest, or pressing the lower back to the floor, can help alleviate muscle spasms. Exercise increases flexibility in tight muscles.
Never rest for more than a few days as movement can increase blood flow in the lower back muscles. Blood carries oxygen and nutrients for healing. Also, always see a doctor for a proper diagnosis.
