Severe Lower Back Pain

Severe Lower Back PainSevere lower back pain can be the result of serious spinal or medical conditions.  While there are many common causes for lower back pain, such as muscle strain and overuse of the muscles, this article focuses on the severe causes of lower back pain.  These severe lower back pain causes can be divided into two main categories – spinal and medical.

Spinal Conditions

Bacterial Infection

Bacteria is generally carried to the spine through your bloodstream from an infection that is located somewhere else in your body or through IV drug use.  It can also enter your spine directly through surgery or injection treatments or from injury.  You may begin to experience lower back pain if the bones in your spinal discs or spinal cord become infected with bacteria.

Ankylosing Spondylitis

This is a form of arthritis or joint inflammation that affects the spine.  It can cause inflammation in your spinal joints or vertebrae that can result in chronic and severe lower back pain.  In many cases that are advanced, new bone can begin to form on the spine, which can cause your spine to fuse into a fixed and immobile position.

Paget’s Disease

This disease causes your bones to grow abnormally.  It also causes your bones to be brittle, enlarged, and not as dense.  Your bones are more prone to breakage with this disease.  It not only affects your spine, but it can also affect your pelvis, chest, legs, and skull.


This occurs when a herniated or ruptured disc presses on your sciatic nerve.  It can cause a shock-like or burning lower back pain combined with pain through the buttocks and down one leg to just below the knee.  It can even reach down to the foot.

Spinal Degeneration

This is generally caused from age and wear and tear.  It can lead to a narrowing of your spinal canal, which can lead to stiffness in your back or pain after walking and standing for long periods of time.


This is a metabolic bone disease that is progressive.  It decreases your bone density and strength.  It can cause brittle, porous bones in your spine and hips when your body is not able to produce new bone.

More Spinal Conditions causing Severe Lower Back Pain

  • Failed Back Surgery Syndrome – This type of severe lower back pain is caused when a surgery does not work to relieve the pain.
  • Spinal Tumors – These are growths that develop on the bones and ligaments of your spine, your spinal cord, or on the nerve roots.
  • Scheuermann’s Disease – This disease causes one or more of the bones of your spine to develop wedge-shaped deformities, which can cause your spine to curve.
  • Ruptured Disc – When a disc degenerates and weakens, cartilage can bulge or push into your spinal cord or nerve root, which can cause severe pain.
  • Spinal Stenosis – This is a narrowing of your spinal canal, which can cause the nerves to pinch causing severe lower back pain.
  • Fibromyalgia – This is a chronic disorder that causes musculoskeletal pain, fatigue, and tender points throughout the entire body.

Medical Conditions

Lower back pain causes do not have to be the result of spinal conditions.  There are other medical conditions that can cause you to have pain in your lower back.  These include, but are not limited to the following:  pelvic inflammatory disease, peptic ulcers, gallbladder disease, pancreatitis, aortic aneurysm, prostate disease, kidney stones, urinary tract infections, and other urinary disorders.

It is absolutely critical that you contact a doctor if you are experiencing severe lower back pain to find out the exact causes before you attempt to relieve the pain yourself.   You could cause more damage if you are not aware of the best methods to treat a particular condition.
