Lower backache can be caused by a variety of factors such as poor posture, muscle strain, weight gain, osteoarthritis, and herniated discs. Generally, lower back pain can be treated with physical therapy, over-the-counter pain medication like ibuprofen and acetaminophen, as well as hot or cold compresses. In serious cases, surgery may be required. To prevent lower backache, individuals should maintain good posture, engage in regular exercise and stretching, and maintain a healthy weight.
