  4. 4.Traumatic Vertebral Fracture

    Vertebral fracture is a fracture or dislocation of a vertebra that can cause bone fragments to pinch and damage the spinal nerves or spinal cord. Most spinal fractures occur from car accidents, falls, gunshot, or sports.

  5. 5.Ankylosing Spondylitis

    Ankylosing spondylitis, also called Bechterew's disease, is a type of arthritis of the spine. 'Arthritis' means inflammation of joints, and in ankylosing spondylitis this means that there is inflammation (irritation and swelling) between the disks that make up the spine. There can also be inflammation between the spine and the pelvis. Bechterew's disease occurs more often in men and in people who have family members with the same disease.

    This is a chronic condition.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, back pain, trouble sleeping, joint pain, hip pain
    Symptoms that always occur with ankylosing spondylitis:
    back pain
    Urgency:
    Primary care doctor
  6. 6.Lower Back Arthritis

    Osteoarthritis, most often simply called arthritis, is a disease of cartilage. In joints, where bones touch and move against one another, cartilage helps provide lubrication for smooth movement, and acts as a shock absorber. Cartilage is also present in between vertebrae, which are the bones comprising the spine. Osteoarthritis of the spine, also known as degenerative joint disease, happens when the cartilage between vertebrae dries out and shrinks. The vertebrae are thus not as able to move smoothly against one another. The ability to walk and perform normal daily activities can be impaired due to inflammation and pain in the lower back.

    Currently, there is no widely accepted cure for osteoarthritis, and medical care is centered on management of symptoms. General pain killers are likely to reduce pain symptoms in the short term (hours up to a day). Corticosteroid injections can reduce pain symptoms for months.

    Rarity:
    Common
    Top Symptoms:
    lower back pain, spontaneous back pain, back pain that gets worse when straightening it, back pain from overuse
    Urgency:
    Primary care doctor
  7. 7.Iliolumbar Syndrome

    Iliolumbar Syndrome is caused by a tear of the iliolumbar ligament, which connects the hip to the spine. It's caused by overuse or acute trauma to the area.

    1-2 months

    Rarity:

    Top Symptoms:
    lower back pain, back pain that shoots to the butt, severe back pain, back pain that shoots to the groin
