You got: Consistent With Ankylosing Spondylitis Hero Images/Getty Images Ankylosing spondylitis is an inflammatory type of arthritis which belongs to a group of conditions known as spondyloarthropathies. Other spondyloarthropathies include psoriatic arthritis, enteropathic arthritis, reactive arthritis, as well as inflammatory bowel diseases. Ankylosing spondylitis primarily affects the back and the neck region. It can involve other joints, too, including the hips, knees, ankles, and shoulders. There can also be systemic effects. While the exact cause of ankylosing spondylitis is unknown, there does seem to be some genetics involved since 90 percent of those with the disease are positive for HLA-B27. It is important to distinguish ankylosing spondylitis from common back pain because treatment approaches can be very different. Moreover, in severe cases of ankylosing spondylitis, the spine can become rigid and can actually fuse. THIS TOOL DOES NOT PROVIDE MEDICAL ADVICE.

Back pain can be caused by injury, osteoarthritis, herniated discs, muscle strain or aches, osteoporosis, and skeletal abnormalities. Risk factors for back pain include age, lack of exercise, overweight, as well as improper body mechanics and improper lifting. It is important to distinguish between common back pain and other conditions which require completely different treatment, such as ankylosing spondylitis. The distinction will be based on imaging studies, blood tests, your medical history, onset of symptoms, and a physical examination. Primarily, common back pain is associated with a mechanical cause while ankylosing spondylitis is an inflammatory disease. Read more on back pain. THIS TOOL DOES NOT PROVIDE MEDICAL ADVICE.
