Herniated Disc or
Lumbar Spinal Stenosis.
Low back pain can happen anywhere below the ribs and above the legs. The
lower back is the connection between the upper and lower body, and it bears
most of the body’s weight. So it's pretty easy to hurt your back when
you lift, reach, or twist. In fact, almost everyone has low back pain at
one time or another.
What causes low back pain?
Causes of low back pain include:
don't really know what causes low back pain. But it is more likely to become
long-lasting (chronic) if you are under stress or depressed.
What are the symptoms?
Depending on the cause, low
back pain can cause a range of symptoms. The pain may be dull or sharp. It may be in one small area or over a broad area. You may have muscle spasms.
Low back pain can also cause leg symptoms, such as pain, numbness, or tingling, often extending below
A rare but serious problem called
cauda equina syndrome can occur if the nerves at the
end of the spinal cord are squeezed. Seek emergency treatment if you have
weakness or numbness in both legs or you lose bladder or bowel control.
Most low back pain is short-term (acute) and will go away in a few weeks. It is more likely to become long-lasting (chronic) if you are depressed or under stress.
How is low back pain diagnosed?
The doctor will
ask questions about your past health, symptoms, and activities. He or she will also do a physical exam. Your answers and the exam
can help the doctor rule out a serious cause for the pain. In most cases,
doctors are able to recommend treatment after the first exam.
X-rays, CT scans, and MRIs don't usually help.
But if you have a back pain problem that has lasted longer than 4 weeks, or if your doctor thinks you may have more than muscle pain, it might be time for one of these tests.
How is it treated?
Most low back pain will improve
with basic first aid, which includes resting for a day or two, getting up and active as soon as possible, and taking over-the-counter pain medicine as needed.
Walking is the simplest and maybe the best exercise for the lower back. It gets your blood moving and helps your muscles stay strong.
