Lower-back spasms can come on suddenly and result in severe back pain and inability to function normally. They may occur from a known injury, or may be the result of improper posture, spinal abnormalities, dehydration, or from any number of other factors.
Ice and Heat
If lower back spasms are caused by an injury, the first line of defence is ice application to reduce swelling and inflammation. After the initial post-injury period, heat is likely to be a more comfortable option to help ease muscle tension.
A massage therapist will use massage techniques, topical analgesics and possibly heat to reduce back pain and release tight muscles that cause spasms.
Over-the-counter non-steroidal anti-inflammatory medications such as ibuprofen or prescriptions from a doctor for muscle relaxants or narcotic pain relievers may be useful in reducing pain from lower back spasms.
When the muscle spasms have been relieved; a course of exercises designed to strengthen the back may be utilised to prevent recurrence.
Working with a chiropractor to keep the spine healthy may be an optimal adjunct in preventing further lower back spasms.
